  [css-anchor-position-1] Document::updateStyleIfNeeded: skip updating style if in the middle of anchor resolution
rdar://141735714
https://bugs.webkit.org/show_bug.cgi?id=285895

Reviewed by Antti Koivisto.

Document::updateStyleIfNeeded should skip updating style if it's in the middle
of style/layout interleaving. This includes the style/layout interleaving
of container query and anchor positioning resolution, however the code wasn't
updated to include the latter case.

* LayoutTests/fast/css/css-anchor-position/anchor-container-crash.html: Added.

* Source/WebCore/dom/Document.h:
(WebCore::Document::isResolvingContainerQueries const):
