Log Message:
-----------
MediaQueryEvaluator::evaluate has repeated computation of RenderStyle
https://bugs.webkit.org/show_bug.cgi?id=293538
rdar://152366637
Reviewed by Sam Weinig.
The MediaQueryEvaluator is creating a new RenderStyle each time.
But this is unnecessary; we don't need a style based on the document's
medium font size to correctly evaluate a media query.
* Source/WebCore/css/query/MediaQueryEvaluator.cpp:
(WebCore::MQ::MediaQueryEvaluator::evaluate const): Use the root element
style instead of creating a new RenderStyle each time.
