On further investigation, I found that the problem can be solved with a
relatively safe change to handle_face_prop, so that it tells
face_at_buffer_position what the base face id is rather than having
face_at_buffer_position recalculate it each time the redisplay loop
wants to display the next face (!). I've checked in the fix.
