Original change's description:
> CSS highlight painting: bump HighlightOverlayPainting to stable
>
> This patch enables the new highlight overlay painter. The rebaselined
> tests and their reasons are as follows:
>
> • no more double painting bug
>     • dark-mode/colors/selection.html
> • originating decorations are now recolored per spec
>     • editing/selection/line-wrap-2.html
>     • virtual/text-antialias/selection/khmer-selection.html
> • spelling markers are now *consistently* painted over text
>     • paint/markers/document-markers-font-8px.html
>     • paint/markers/document-markers-zoom-2000.html
> • decorations are now clipped to highlight background rect
>     • svg/text/text-selection-deco-01-b.svg
>     • svg/text/text-selection-text-03-b.svg
>
> The only new failure expectations are as follows:
>
> • external/wpt/css/css-pseudo/highlight-painting-003.html broadens
>   from Mac11 to Mac (like we had to do in CL:3608432)
> • external/wpt/css/css-text-decor/text-decoration-color-selection-001
>   fails because the test is incorrect (bug 1321106)
> • paint/markers/suggestion-marker-basic.html fails because it’s not
>   clear the assertion still complies with the spec (bug 1321114)
>
> Some tests had bugs that we’ve fixed in this patch:
>
> • external/wpt/css/css-pseudo/target-text-text-decoration-001.html
>   had a bug where it assumed UA default highlight colors would be
>   suppressed by an author ‘text-decoration’
>
