bug#13225: 24.3.50; Non-selected window has not mode-line-inactive face

Ah, yes, that makes sense.
Of course, when we drop frame-local variables this problem
will disappear.

Maybe we should live with the "selected_frame->selected_window !=
selected_window" problem until we get rid of frame-local vars.
