Comments
EVALUATION Due to 6797728 hints are now off in both FM and AA are set. Therefore umlaut is shifted by a fraction, presumably because the hints were doing some adjustment. This is intended change and not regression per se. Therefore we need to update test. In this particular case we can remove one of AA or FM hints. Note that we might also need to update test/golden images for 4322332 if we have them.
