Chromium Issue

Description

Fixed a long-standing WPT failure in CSS text line breaking:
css/css-text/word-break/word-break-break-all-ethiopic.html.

Fix

Fix word-break: break-all behavior by honoring UAX#14 LB21 in the break-all line break table and removing incorrect break opportunities before BA-class characters (for example U+1361 Ethiopic Wordspace).
