The script transport used to evaluate fetched script sources which is
undesirable for unsuccessful HTTP responses. This is different to other data
types where such a convention was fine (e.g. in case of JSON).

Calling `Array.prototype.concat.apply( [], inputArray )` to flatten `inputArray`
crashes for large arrays; using `Array.prototype.flat` avoids these issues in
browsers that support it. In case it's necessary to support these large arrays
even in older browsers, a polyfill for `Array.prototype.flat` can be loaded.
This is already being done by many applications.

IE/Edge sometimes crash when comparing documents between frames using the strict
equality operator (`===` & `!==`). Funnily enough, shallow comparisons
(`==` & `!=`) work without crashing.

`:even` & `:odd` are deprecated since jQuery 3.4.0 & will be removed in 4.0.0.
The new `even()` & `odd()` methods will make the migration easier.

With new selector code doing less convoluted support tests, it was possible
to extract a lot of logic out of setDocument & also reduce size.
This commit also backports jquery/sizzle#439 that was reverted by mistake
during a switch from JSHint + JSCS to ESLint.

Previously, jQuery.ajaxSettings.xhr, contents were wrapped in a try-catch
as we defined jQuery.support.ajax & jQuery.support.cors executed during the
jQuery load and we didn't want to crash if IE had native XHR disabled (which
is possible). While jQuery hasn't supported the ActiveX-based XHR since 2.0,
jQuery with XHR disabled could still be used for its other features in such
a crippled browser.
Since gh-4347, jQuery.support.ajax & jQuery.support.cors no longer exist, so
we don't need the try-catch anymore.

The `:scope` pseudo-class[1] has surprisingly good browser support: Chrome,
Firefox & Safari have supported if for a long time; only IE & Edge lack support.
This commit leverages this pseudo-class to get rid of the ID hack in most cases.
Adding a temporary ID may cause layout thrashing which was reported a few times
in [the past.
We can't completely eliminate the ID hack in modern browses as sibling selectors
require us to change context to the parent and then `:scope` stops applying to
what we'd like. But it'd still improve performance in the vast majority of
cases.

This commit removes Sizzle from jQuery, inlining its code & removing obsolete
workarounds where applicable.
The selector-native module has been removed. Further work on the selector
module may decrease the size enough that it will no longer be necessary. If
it turns out it's still useful, we'll reinstate it but the code will look
different anyway as we'll want to share as much code as possible with
the existing selector module.
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 commit reduces the gzipped jQuery size by 1460 bytes compared to master.
Closes gh-4395
Apart from porting most Sizzle tests to jQuery (mostly to its selector module),
this commit fixes selector-native so that a jQuery custom compilation that
excludes Sizzle passes all tests as well.

This commit requires all function parameters to be used, not just the last one.
In cases where that's not possible as we need to match an external API, there's
an escape hatch of prefixing an unused argument with `_`.
This change makes it easier to catch unused AMD dependencies and unused
parameters in internal functions the API of which we may change at will, among
other things.
Unused AMD dependencies have been removed as part of this commit.
Closes gh-4381
The original fix didn't account for the fact that in IE `<object>` elements
with no `data` attribute have an object `contentDocument`. The fix leverages
the fact that this special object has a null prototype.

Because of the above conditional, the 'type' variable has a value of type
'string' or undefined. Therefore, boolean comparisons for 'type' variable
is always unnecessary because it return true. The patch removed the
unnecessary conditional statement.

A leftover `rboxStyle` was left in the wrapper parameters but not in the
dependency array, causing `getStyles` to be undefined in AMD mode.
Since `rboxStyle` is no longer used, it's now removed.

Latest versions of all browsers now implement focusin & focusout natively
and they all converged on a common event order so it doesn't make much sense
for us to normalize it to a different order anymore.
Note that it means we no longer guarantee that focusin fires before focus
and focusout before blur.
Fixes gh-4300
Closes gh-4362
The camelCase implementation used by the data module no longer turns `-ms-foo`
into `msFoo` but to `MsFoo` now. This is because `data` is supposed to be
a generic utility not specifically bound to CSS use cases.

Summary of the changes/fixes:
1. Trigger checkbox and radio click events identically (cherry-picked from
b442abacbb that was reverted before).
2. Manually trigger a native event before checkbox/radio handlers.
3. Add test coverage for triggering namespaced native-backed events.
4. Propagate extra parameters passed when triggering the click event to
the handlers.
5. Intercept and preserve namespaced native-backed events.
6. Leverage native events for focus and blur.
7. Accept that focusin handlers may fire more than once for now.

PR #3869 added support for `<script type="module">` & some support for
the `nomodule` attribute but with no tests for `nomodule` and with the
attribute only respected on inline scripts. This commit adds support for
source-based scripts as well. It also adds tests for `nomodule`, including
making sure legacy browsers execute such scripts as they'd natively do - that's
the whole point of `nomodule` scripts, after all.

- getResponseHeader(key) combines all header values for the provided key into a
single result where values are concatenated by ', '. This does not happen for
IE11 since multiple values for the same header are returned on separate lines.
This makes the function only return the last value of the header for IE11.

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.
