Some recently added tests are not compatible with old Tk versions. I have build all 8.5 and 8.6 versions and build and test Tkinter against them. The proposed PR makes tests passes on Tk versions 8.5.4 to 8.5.19 and 8.6.0 to 8.6.12. There are some issues with running the pure Tk shell for versions < 8.5.4 so I skipped them.

Is support for such old Tk versions useful? 8.5.4 was released in late 2008, and I highly doubt anyone would still be using it. IMO, 8.5.12 would be a good compromise, since we're giving support to a version more than 9 years old, but would simplify PR-29913 by removing several 8.5.x specific branches. (FYI, 8.5.12 was released on 2012-07-27 and 8.6.0 on 2012-12-20)

It is a great idea. I have opened bpo-46996 for this.
