Thanks.

This is how Emacs display engine always worked: the non-text parts of
the window display are drawn in the default face.  (Remapping does not
change the default face, as far as Emacs internals are concerned, it
just substitutes a different face in its stead, leaving the literal
DEFAULT_FACE_ID intact.)

So this bug has rather low priority at this time, as it's not a
regression wrt Emacs 23.  Time permitting, I will at the very least
try to figure out what changes are needed to make this work as
expected.
