Crash in WebCore::RenderFragmentedFlow::objectShouldFragmentInFlowFragment
https://bugs.webkit.org/show_bug.cgi?id=286019
<rdar://problem/142992656>
Reviewed by Antti Koivisto.
This patch ensures that RenderFragmentedFlow does not crash when its state is
stale due to
being inside a skipped subtree.
m_fragmentsInvalidated gets cleared at layout but skipped content subtree does
not necessarily run layout (unless forced).
Test case credit goes to Claudio Saavedra (csaave...@igalia.com).
