When collapsing panels in code, relinquish focus immediately,
triggering an immediate reeval of current focus in WM,
triggering an immediate reeval of sysui flags,
triggering an immediate system bar transition
with the correct destination content frame.
Otherwise we eventually get around to it, after several layers
of sysui animation delays, but delaying the sysui visibility
re-eval until this point is far too late.
