Incorrect tab stop if tab-size is a <length> and the distance to the next tab
stop is less than 0.5ch
https://bugs.webkit.org/show_bug.cgi?id=258961
Reviewed by Myles C. Maxfield.
FontCascade::tabWidth returns the width between the current
position and the next tab stop. If it is less than 0.5ch, it
should return the width between the current position and the next
next tab stop.
<https://drafts.csswg.org/css-text-3/#white-space-phase-2>
The width of the next next tab stop is the sum of the width of
the next tab stop and the tab size. However, it just returned the
tab size in the case.
This change makes the following wpt tests pass.
