This reverts commit c6bfb8a155.
Reason for revert: This change broke Narrator's move-by-headings
feature. Heading navigation is a critical feature of screen readers that
facilites navigating web pages, like the google/bing results page. It
impacts all headings throughout the web, whereas the original CL was
fixing a scoped problem: spelling errors unannounced when exposed using
CSS highlights. We will also revert this change from 134.
Original change's description:
> [a11y] Fixes move by format for CSS spellcheck highlights
>
> Uses Spelling/Grammar error CSS highlight markers in the
> Accessibility Tree to break format boundaries around those
> errors to help navigate better around these spelling/grammar
> errors.
>
> This CL achieves following:
> 1) Fixes Move by format to accommodate CSS spellcheck highlights.
> 2) Narrator calls out the spelling issues correctly.
