It appears to me that the internal focus should already have changed when
the WM_KILLFOCUS is received (see windows/focus.c), and that if this is
the case, it should know that it doesn't have to send more WM_KILLFOCUS
messages in a recursion. You may want to find out why that doesn't work.

I suspect something in winpos.c after line 1823 may not do such a check.
