  REGRESSION(265827 at main): Variable reference in matched declarations cache can not be overridden
https://bugs.webkit.org/show_bug.cgi?id=259112
rdar://111924949

Reviewed by Myles C. Maxfield.

A normal non-inherited value overriding a variable reference may not be applied correctly.

* LayoutTests/fast/css/variables/variable-reference-override-cached-expected.html: Added.
* LayoutTests/fast/css/variables/variable-reference-override-cached.html: Added.
* Source/WebCore/style/PropertyCascade.cpp:
(WebCore::Style::PropertyCascade::hasProperty):
(WebCore::Style::PropertyCascade::addMatch):
(WebCore::Style::PropertyCascade::shouldApplyAfterAnimation):

The cached variable reference case needs the same already-applied check as the after-animation case.
Move the check to addMatch.
