Summary: Possible transient bug

Initial Comment:
This code on Windows using ActiveTcl 8.4.1:

toplevel .foo

toplevel .moo
update idletasks
wm transient .moo .foo
grab set .moo

toplevel .boo
update idletasks
wm transient .boo .moo
grab set .boo

toplevel .bar
update idletasks
wm transient .bar .boo
grab set .bar

Creates the proper windows.  Then, double-click the
taskbar, iconifying the application.  Now, click the
taskbar icon again, deiconifying the application. 
Every window except the top one, .bar, come back.  The
state of .bar is still withdrawn for some reason.  And,
if you attempt to deiconify it, it draws the title bar
and an outline of the window but never finishes.  It
hangs there.

The script that I developed before finding this tracker item was:

package require Tk
wm dei .    ; wm geo . +100+100
toplevel .t ; wm geo .t +100+500
toplevel .s ; wm geo .s +500+100
toplevel .u ; wm geo .u +500+500
wm trans .t .
wm trans .s .t
wm trans .u .s

Message:
This problem (specifically, that .bar is never redrawn anymore) appears to
affect Tk 8.5.9 on Windows 7 and Tk 8.6b2 on an unreported version of
Windows.  I believe I've traced it as far as WM_PAINT events not arriving
in TkWinChildProc for the window.
