The mouse-face is merged with whatever underlying faces are in the buffer in
the highlighted region, so you can't just have one precomputed mouse-face.
I suppose you could have redisplay notice which regions might be highlighted,
and pre-cache the corresponding mouse-face/buffer-face combination so that it
doesn't happen at highlighting time, but I don't know how easy this would be
(and if the face cache gets flushed at the wrong toime, you have a problem!).
