This also affects many, if not all, VB6 applications (and possibly many 
Delphi applications). Personally, I consider this a rather serious 
regression and propose backing out of commit 
cb3ff54789c652b02d852f40db71cafd9fd67ca9 as a fix.

BTW, this reminds me of bug 1598. If the explanation of the bug for IDA 
above is correct, then the "buggy" behavior of not assigning 
minimize/maximize buttons to the window that appears in the panel is 
sort of consistent with this regression. Maybe the behavior should be 
that visible windows owned by an invisible window should get mapped in 
the panel.
