[Repaint] Changing text-decoration-color on ancestor block has no affect on
inline content
https://bugs.webkit.org/show_bug.cgi?id=292373
Reviewed by Antti Koivisto.
Text decoration properties are propagated to descendant content even crossing
block containers.
e.g.
<div style="text-decoration-color: red"><div><div>this should have red
decoration color</div></div></div>
This is achieved in TextBoxPainter by climbing the ancestor chain collecting
text decoration related values (as opposed to through style inheritance).
Considering this propagating behavior StyleDifference::RepaintIfText was never
a valid repaint optimization for text-decoration.
