Hi Ned,  I think this problem is fixed now in the tip of the Tk macosx_filedialog branch.  I am attaching the tkMacOSXDialog.c file from that branch.  I think you should be able to just replace the version in 8.6.11 and be able to build a working version.  I have tested on macOS 10.14, 10.15, 11 and 12.  Can you please test on your systems?

If it looks OK I will merge the changes into 8.6.12-rc so they will appear in the 8.6.12 release when that happens.  It should be fairly soon.
