This change is not related but I found it while working on jquery/jquery#5113 and discovering removal of this workaround breaks the relevant test in IE 9.

Good use of CSS.supports with :is!

Sizzle has followed the following logic for selector handling for ages:
1. Modify the selector to adhere to scoping rules jQuery mandates.
2. Try `qSA` on the modified selector. If it succeeds, use the results.
3. If `qSA` threw an error, run the Sizzle custom traversal instead.
It worked fine so far but now CSS has a concept of forgiving selector lists that
some selectors like `:is()` & `:has()` use. That means providing unrecognized
selectors as parameters to `:is()` & `:has()` no longer throws an error, it will
just return no results. That made browsers with native `:has()` support break
selectors using jQuery extensions inside, e.g. `:has(:contains("Item"))`.
Detecting support for selectors can also be done via:
```js
CSS.supports( "selector(SELECTOR_TO_BE_TESTED)" )
```
which returns a boolean. There was a recent spec change requiring this API to
always use non-forgiving parsing:
w3c/csswg-drafts#7280 (comment)
However, no browsers have implemented this change so far.
To solve this, two changes are being made:
1. In browsers supports the new spec change to `CSS.supports( "selector()" )`,
use it before trying `qSA`.
2. Otherwise, add `:has` to the buggy selectors list.

`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. Fixes jquery/jquery#5194 Ref jquery/jquery#5098 Ref jquerygh-486 Ref w3c/csswg-drafts#7676
