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. [1] https://developer.mozilla.org/en-US/docs/Web/CSS/:scope Fixes gh-4453 Closes gh-4454 Ref gh-4332 Ref jquery/sizzle#405 |
