[Remote Inspection] Add a mechanism to adjust visibility for the purposes of
painting underneath element subtrees
https://bugs.webkit.org/show_bug.cgi?id=271332
Reviewed by Antti Koivisto and Anne van Kesteren.
This patch consists of the following:
1. An `ElementRareData` flag to mark elements as "visibility adjustment roots".
2. A new `RenderStyle` flag that's set at style adjustment time, after
consulting (1). This new
flag is used to implement a notion of `usedVisibility()`, wherein the
visibility used for
painting, hit-testing, accessibility, and some other purposes that are
opaque to script may
differ from the specified visibility.
3. Finally, deploy this new `usedVisibility()` method in all places where
`visibility()` is
currently used for non-web-exposed purposes.
In subsequent patches, this style infrastructure will make it possible for Web
Inspector's Element
Selection targeting mode to inspect elements that would otherwise be obscured
by other content,
without running into compat issues that may arise from affecting the computed
visibility in a way
that the page's script may not expect or handle correctly.
See below for more details.
