Daniel Steffen provided me a patch for the issue that he devised during 
the development of Mavericks, and which he applied to Apple's private 
branch of Tk-Cocoa (essentially the old 8.5.9 branch, as you noted in 
the bug report). Daniel's patch is why the behavior isn't visible in 
Apple's system-provided Tk, because it was fixed already. :-) Now that 
Mavericks is out he was able to provide the patch for upstream use.

After installing Mavericks and testing with my existing build of Tk, I 
did see the behavior. After doing a fresh checkout of trunk and 8.5, 
applying the patch, and rebuilding Tcl/Tk, I don't see any of the 
behavior indicated. As a result I believe this patch solves the problem 
and I have committed it.

Thanks again for the report, and thanks to Daniel for the patch.

Best,
Kevin
