test case

WebCore does not invalidate enough lines when editing bidi text

Because of how we cache BidiStatus objects on RootLineBoxes, we need to be careful to re-run enough of the Unicode Bidi Algorithm (BidiResolver) during editing, if we are removing/adding strong characters which could affect preceding neutral/mirrored characters.
