Chrome 112 & Safari 16.4 introduce two changes:
* `:has()` is non-forgiving
* `CSS.supports( "selector(...)" )` parses everything in a non-forgiving way
We no longer care about the latter but the former means the `cssHas` support
test now passes.
Closes gh-5226
In IE (all versions), `focus` & `blur` handlers are fired asynchronously
but `focusin` & `focusout` are run synchronously. In other browsers, all
those handlers are fired synchronously. Asynchronous behavior of these
handlers in IE caused issues for IE (gh-4856, gh-4859).
We now simulate `focus` via `focusin` & `blur` via `focusout` in IE to avoid
these issues. This also let us simplify some tests.
This commit also simplifies `leverageNative` - with IE now using `focusin`
to simulate `focus` and `focusout` to simulate `blur`, we don't have to deal
with async events in `leverageNative`. This also fixes broken `focus` triggers
after first triggering it on a hidden element - previously, `leverageNative`
assumed that the native `focus` handler not firing after calling the native
`focus` method meant it would be handled later, asynchronously, which
was not the case (gh-4950).
To preserve relative `focusin`/`focus` & `focusout`/`blur` event order
guaranteed on the 3.x branch, attach a single handler for both events in IE.
A side effect of this is that to reduce size the `event/focusin` module
no longer exists and it's impossible to disable the `focusin` patch
in modern browsers via the jQuery custom build system.

`CSS.supports( "selector(...)" )` has different semantics than selectors passed
to `querySelectorAll`. Apart from the fact that the former returns `false` for
unrecognized selectors and the latter throws, `qSA` is more forgiving and
accepts some invalid selectors, auto-correcting them where needed - for
example, mismatched brackers are auto-closed. This behavior difference is
breaking for many users.
To add to that, a recent CSSWG resolution made `:is()` & `:where()` the only
pseudos with forgiving parsing; browsers are in the process of making `:has()`
parsing unforgiving.
Taking all that into account, we go back to our previous try-catch approach
without relying on `CSS.supports( "selector(...)" )`. The only difference
is we detect forgiving parsing in `:has()` and mark the selector as buggy.
The PR also updates `playwright-webkit` so that we test against a version
of WebKit that already has non-forgiving `:has()`.

So far, we've been running browser tests on GitHub Actions in Chrome
and Firefox. Regular Safari is not available in GitHub Actions but
Playwright WebKit comes close to a dev version of Safari.
With this change, our GitHub CI & local test runs will invoke tests on
all actively developed browser engines on all PRs.
Also, our GitHub Actions browser tests are now running on Node.js 18.
Detection of the Playwright WebKit browser in support unit tests is done
by checking if the `test_browser` query parameter is set to `"Playwright"`;
this is a `karma-webkit-launcher` feature. Detecting that browser via
user agent as we normally do is hard as the UA on Linux is very similar
to a real Safari one but it actually uses a newer version of the engine.
In addition, we now allow to pass custom browsers when one needs it;
e.g., to run the tests in all three engines on Linux/macOS, run:
```
grunt && BROWSERS=ChromeHeadless,FirefoxHeadless,WebkitHeadless grunt karma:main
```

This commit removes Sizzle from jQuery, inlining its code & removing obsolete
workarounds where applicable.
The Sizzle AUTHORS.txt file has been merged with the jQuery one - people are
sorted by their first contributions to either of the two repositories.
The main `selector` module can be disabled in favor of `selector-native`
via:
grunt custom:-selector
For backwards compatibility, the legacy `sizzle` alias is also supported (it
will be dropped in jQuery `4.0.0`):
grunt custom:-selector
Sizzle tests have been ported to jQuery ones. Ones that are not compatible
with the `selector-native` module are disabled if the regular selector module
is excluded.
Backwards compatibility is still kept for all `Sizzle` utils - they continue to be
available under `jQuery.find` - but the primary implementation is now attached
directly to jQuery.
Some selector utils shared by `selector` & `selector-native` have been
extracted & deduplicated. `jQuery.text` and `jQuery.isXMLDoc` have been
moved to the `core` module.
The commit reduces the gzipped jQuery size by 851 bytes compared to the
`3.x-stable` branch.

Introduces a new test API, `includesModule`. The method returns whether
a particular module like "ajax" or "deprecated" is included in the current
jQuery build; it handles the slim build as well. The util was created so that
we don't treat presence of particular APIs to decide whether to run a test as
then if we accidentally remove an API, the tests would still not fail.

This is a version of gh-4993 for the `3.x-stable` branch.
The GitHub UI treats `#NUMBER` as referring to its own issues which is confusing
when in jQuery source it's usually referring to the old deprecated Trac instance
at https://bugs.jquery.com. This change replaces all such Trac references with
`trac-NUMBER`.
A few of the references came with the Sizzle integration and referred to the
Sizzle GitHub bug tracker. Those have been replaced with full links instead.
A new entry describing issue reference conventions has been added to README.

Firefox incorrectly (or perhaps correctly) includes table borders in computed

Closes gh-4807
This commit fixes unit tests for the following builds:
1. The no-deprecated build: `custom:-deprecated`
2. The current slim build: `custom:-ajax,-effects`
3. The 4.0 (#4553) slim build: `custom:-ajax,-callbacks,-deferred,-effects`
It also adds separate Travis jobs for the no-deprecated & slim builds.
Apart from that, add intuitive names to Travis jobs. Otherwise it's hard to see
at a glance that a particular job is running on Firefox ESR, for example.

Android was catching the generic iOS regex. Checking for Android first should
eliminate that issue as iOS user agents don't contain the word "Android".
Putting Safari last makes Android UAs not be tested against it.
The regexes detecting browsers with their versions have been updated for iOS
and Safari so that all iOS >=11 & all Safari (desktop) >= 11 are recognized.
This is required to make Safari 13 & iOS 13 pass support tests but it'll also
make tests forward-compatible with future Safari/iOS versions.

Also, run `grunt npmcopy` to sync the "external" directory with dependencies

Current width/height cssHook reads the computed position style even if not
necessary as the browser passes the scrollboxSize support test. That has been
changed.
This commit also makes the scrollboxSize support test in line with all others
(i.e. only return true or false) and changes the variable name in the hook
to make the code clearer.

The user agent of the iPad with iOS 11.3 on BrowserStack is missing the "iPhone"
part in the "iPhone OS 11_3" part. This commit makes the iOS regex accept such
(probably?) malformed UAs.
A whitelist is available so that some tests can be allowed to always succeed.
This is used only for ajax for now as it can be manually disabled in IE but
is enabled by default.
