+ Have fixedPositionCreatesStackingContext be on by default everywhere
+ https://bugs.webkit.org/show_bug.cgi?id=169334
+
+ Reviewed by Zalan Bujtas.
+
+ It makes no sense to have web-exposed CSS functionality be different based on setting,
+ and other browser are now aligned with having position:fixed create stacking context.
+
+ So remove the fixedPositionCreatesStackingContext setting and have StyleResolver::adjustRenderStyle()
+ always force stacking context for position:fixed.
