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.

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.

The test for Shadow DOM v1 support has been changed to rely on the presence of
`documentElement.getRootNode` as iOS 10.0-10.2 supports `attachShadow` but
doesn't support `getRootNode`.
No new test is necessary - iOS 10.0 fails lots of our test suite because of
this bug.

Android Browser disregards td's box-sizing, treating it like it was content-box.
Unlike in IE, offsetHeight shares the same issue so there's no easy way to
workaround the issue without incurring high size penalty. Let's at least check
we get the size as the browser sees it.
Also, fix the nearby support comment syntax.

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.

So far, we've been testing that jQuery element iteration works with polyfilled
Symbol & transpiled for-of via a Node test with jsdom with the Symbol global
removed. Unfortunately, jsdom now requires Symbol to be present for its internal
functionality so such a test is no longer possible. Instead, it's been migrated
to an iframe test with transpiled JavaScript.
This PR also enables us to use ECMAScript 2017 or newer in Node.js code.

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

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

Edge sometimes doesn't execute module scripts. It needs to be investigated why

In Edge 14-16 setting a style property to a whitespace-only value resets it to

rAF logic was introduced almost three years ago relative to this commit,
as a primary method for scheduling animation (see gh-1578 pull).
With it there was two substantial changes - one was explicitly mentioned
and the other was not.
First, if browser window was hidden aka `document.hidden === true`
it would immediately execute all scheduled animation without waiting
for time pass i.e. tick time become `0` instead of 13 ms of a default value.
Which created possibility for circular executions in case if `complete`
method executed the same animation (see gh-3434 issue).
And the second one - since then there was two ways of scheduling animation:
with `setInterval` and `requestAnimationFrame`, but there was a
difference in their execution.
In case of `setInterval` it waited default `jQuery.fx.interval` value before
actually starting the new tick, not counting the first step which wasn't
set to be executed through tick method (aka `jQuery.fx.tick`).
Whereas `requestAnimationFrame` first scheduled the call and executed
the `step` method right after that, counting the first call of
`jQuery.fx.timer`, `tick` was happening twice in one frame.
But since tests explicitly disabled rAF method i.e.
`requestAnimationFrame = null` and checking only `setInterval` logic,
since it's impossible to do it otherwise - we missed that change.
Faulty logic also was presented with `cancelAnimationFrame`, which couldn't
clear any timers since `raf` scheduler didn't define new `timerId` value.
Because that change was so subtle, apparently no user noticed it proving
that both `cancelAnimationFrame` and `clearInterval` code paths are redundant.
Since `cancelAnimationFrame` didn't work properly and rAF is and was a primary
used code path, plus the same approach is used in other popular animation libs.
Therefore those code paths were removed.
These changes also replace two different functions which schedule the animation
with one, which checks what type of logic should be used and executes it
appropriatley, but for secondary path it now uses `setTimeout` making it more
consistent with rAF path.
Since ticks are happening globally we also don't require to listen
`visibilitychange` event.
It also changes the way how first call is scheduled so execution of
animation will not happen twice in one frame.
No new tests were not introduced, since now `setTimeout` logic should be
equivalent to the rAF one, but one test was changed since now we actually
execute animation at the first tick.

1. Use the short name of the preset in the config.
2. Run ESLint first on non-minified files.
3. Explicitly specify environments in every config file (those settings cascade
which means we've been assuming a Node.js environment where we shouldn't have).
- Renames and changes rnotwhite to focus on HTML whitespace chars
- Change internal use of jQuery.trim to more accurate strip and collapse
- Adds tests to ensure HTML space characters are retained where valid
- Doesn't add tests where the difference is inconsequential and
existing tests are adequate.

Working around this problem would require us to skip setting whitespace-only
values except when they're valid which would be very fragile. Another option
would be to set the value and see if it succeeded and then react to that.
We've tried something like that in the past to be able to overwrite !important
styles (see 24e5879) but it broke the CSS cascade (see
https://bugs.jquery.com/ticket/14836#comment:5) and was triggering
MutationObserver callbacks too often so it was reverted in PR gh-1532.
