For some value of "proper".

It should be.  Just that we need the right argument for it which is, in
the case at hand, the frame hosting the window returned by
'get-mru-window' with ALL-FRAMES set to all visible frames with the same
root frame as the frame we just made invisible.  If there's no other
child frame this will return the root frame of the frame that has been
made invisible just now.  Elementary, but splicing in the root frame
into 'get-mru-window' is not straightforward.  The same approach is
probably also needed when deleting or iconifying a child frame.  I'll
try to make this work.  Till then we could try to use the root frame as
argument.
