Revert of Invalidate whitespace text on text color changes

Revert of Invalidate whitespace text on text color changes (patchset #3 id:40001 of https://codereview.chromium.org/1332233002/ )

Reason for revert:
Caused a perf regression on https://chromeperf.appspot.com/report?sid=853c237ff4d1aba523371425b1de88bf28b30ae72464c956409b9a5874a5afd2

Original issue's description:
> Invalidate whitespace text on text color changes
> 
> This patch updates the optimization added in [1] to invalidate
> whitespace text on color changes because whitespace text can have
> decorations such as underlines which still need to repaint.
> 
> The big idea of the optimization in [1] is to not unnecessarily repaint
> expensive items such as images that are in an <a> element. On hover, <a>
> will change color and underline styles which should not affect images.
> This patch adds a test to prove this optimization still works and
> prevents it from breaking in the future.
>
