        return;

    bidiResolver.setStatus(BidiStatus(run.direction(), run.directionalOverride()));
    bidiResolver.setPositionIgnoringNestedIsolates(TextRunIterator(&run, 0));

    // FIXME: This ownership should be reversed. We should pass BidiRunList
    // to BidiResolver in createBidiRunsForLine.
    BidiRunList<BidiCharacterRun>& bidiRuns = bidiResolver.runs();
