The style candidate cache had regressed a few times (see #12534), and my intuition is that being able to disable all style sharing with a single rule in the page is really unfortunate. This commit redesigns the style sharing cache in order to be a optimistic cache, but then reject candidates if they match different sibling-affecting selectors in the page, for example. So far the numbers have improved, but not so much as I'd wanted (~10%/20% of non-incremental restyling time in general). The current implementation is really dumb though (we recompute and re-match a lot of stuff), so we should be able to optimise it quite a bit. I have different ideas for improving it (that may or may not work), apart of the low-hanging fruit like don't re-matching candidates all the time but I have to measure the real impact. Also, I need to verify it against try.
