Just like it has always worked in Core. This will help with size comparisons
between 1.13 & 1.14.
After this PR:

Before, only the less interesting `raw` sizes were reported.

jQuery 3.6 has issues with focus handling in IE which breaks this test.
The issues were fixed in jQuery 3.7, so we just accept them here.
Closes gh-2231
One of the changes is increasing `revertDuration` from 200 to 300. For some
reason, when jQuery 3.1 is used in an iframe (which TestSwarm uses) the timings
are lower than expected and `setTimeout` too slow and the check for animation
happens too late.
Closes gh-2230
The test "#8958: dialog can be opened while opening" had special behavior in
jQuery 1.8 and the patch from commit 7adb13ac7c
broke those assumptions. Adjust the test so that it passes again.
Closes gh-2229
In IE, `option` elements may have different initial `option` colors.
They may initially all be transparent, but later the selected
option gets a blue background with white text; we now ignore it.
The logic of `qunit-assert-domequal` was also fixed to use the same
method of fetching styles in all browsers; IE used to get a legacy
one meant for IE <9 due to a mistake in the performed check.
jQuery 3.0 & 3.1 used `getBoundingClientRect()` in its `width`/`height`
calculations and that causes minor differences in fractional width computations.
Allow a tiny delta in tests to fix those tests breaking in Firefox.

The workaround triggering a second delayed focus to a tabbable element was
applied in jQueries 3.4 & 3.5 to fix IE issues. It also needs to be applied
in jQuery 3.6 which this commit adds.
This will no longer be needed in jQuery 3.7 and jQuery 3.x-git tests are
already passing because of that.
Closes gh-2160
Change a2b25ef6ca made options with
the `hidden` attribute skipped when rendering. However, that makes
indexes misaligned with native options as hidden ones maintain their
index values. Instead, don't skip hidden options but add the `hidden`
attribute to the respective jQuery UI elements as well.
Fixes gh-2082
Closes gh-2144

Changes:
* add `tests/lib/vendor/**/*` to `.eslintignore`
* move `qunit-composite` to `tests/lib` so that we can modify it
* move `qunit-assert-classes` to `tests/lib` so that we can modify it
* move `qunit-assert-close` to `tests/lib` so that we can modify it
* replace `assert.push` with `assert.pushResult`
* remove usage of `QUnit.extend`
Closes gh-2157
Also, workaround issues with QUnit Chrome bridge: the Chrome bridge
from `grunt-contrib-qunit` is now getting injected into every single
iframe, including an empty one that has no intention of running QUnit
tests. Since that bridge requires QUnit, it fails with an error
in such cases. Workaround the issue by wrapping the bridge in
another function that bails early if QUnit is not defined.

Self-closing tags are reported by newer versions of the htmllint
Grunt plugin. They also don't make sense in our HTML files
since they are not XHTML-compliant and they run in HTML mode
anyway.

The docs say that valid periods when using string value and
period pairs as relative dates are "y", "m", "w", and "d"
