[css-anchor-position-1] Invalidate all remembered last successful position
option when @position-try mutates
rdar://162555785
https://bugs.webkit.org/show_bug.cgi?id=300657
Reviewed by Antti Koivisto.
This patch invalidates all remembered last successful position option when a
property inside @position-try rule mutates, per spec. This is done by making
PropertySetCSSDescriptors::setPropertyInternal virtual, and providing an
override
in CSSPositionTryDescriptors that invalidates the remembered position options.
This is the bare minimum needed to pass the test.
