Bug 1996030 [wpt PR 55623] - Fix detection of document transition in ScopedPauseRendering., a=testonly
Automatic update from web-platform-tests
Fix detection of document transition in ScopedPauseRendering.
If the <html> element is replaced, the ViewTransition::scope_ may still
refer to the old document element. Relying on IsDocumentElement() leads
to a crash as described in the bug.
