Indeed this doesn't work any more. This was one of the very few places
where (eq (frame-selected-window) (selected-window)) was nil, and this
"invariant" is presumed at various places in the C code, so it was
a bug.
BTW, this worked in Emacs<24.3 if you wanted to highlight every frame's
selected-window, but not if you wanted to highlight "the one and only
selected-window". For single-frame settings, there's no difference,
of course.
There is no alternative, yet. We should probably provide some ad-hoc
primitives (call them maybe display-selected-window and
display-frame-selected-window) which return something like "the window
that was selected when we entered redisplay".
