Unlike CSS animations/transitions, script animations keep alive on display:none
elements, so once the display property was changed to others in normal
styling, we need to do styling for the script animations in the second
animation traversal. Otherwise, the styling for the script animations will
be deferred to the next frame.
* Make `SelectorFlagsMap::apply_flags` private so it's easier to ensure
it is called from the correct thread.
* Clear the cache and the map at the same time; otherwise it leaves
`SelectorFlagsMap` in an inconsistent state.
This code used to insert duplicate entries to avoid expensive shuffling
of the LRU cache. With uluru this is no longer necessary, because
reordering the cache is cheap.
Now it uses the `LRUCache::find` method from uluru 0.2 to update entries
in-place. This should improve the hit rate, because it eliminates
unnecessary evictions.
It's out-of-band data I never liked, and the code has changed enough from when
it was introduced, that now all of the information it stores can be local.
