When the cursor moves, w->phys_cursor.x is recomputed. AFAIR, in this
case we perform the usual redisplay (which updates w->phys_cursor),
and then reapply mouse-face, so show_mouse_face should be called
again. But you can easily establish if I'm right by running Emacs in
a debugger with a breakpoint in show_mouse_face. Let me know if you
find something unexpected or need help in interpreting the findings.
