Selector: Re-expose jQuery.find.tokenize

mgol · mgol · commit 6a2c60c66977 · 2023-05-30T00:14:57.000+02:00
`Sizzle.tokenize` is an internal Sizzle API, but exposed. As a result, it has historically been available in jQuery via `jQuery.find.tokenize`. That got dropped during Sizzle removal; this change restores the API. In addition to that, Sizzle tests have been backported for the following APIs: * `jQuery.find.matchesSelector` * `jQuery.find.matches` * `jQuery.find.compile` * `jQuery.find.select` * `jQuery.find.tokenize` Fixes jquerygh-5259 Ref jquery/sizzle#242 Ref jquerygh-5113 Ref jquerygh-4395 Ref jquerygh-4406
