Travis failure is unrelated but I don't know that it should be ignored. I restarted that one test.

Same error on rerun.

@ambv @ned-deily If the next 3.8 is going to have a macox11 installer, then this should be merged, (I believe Ned requested the backport.) But I don't know what to do about the repeated failure.

@terryjreedy, you are not alone in seeing 3.8 CI failures, see https://bugs.python.org/issue42574. At the moment, support for macOS Big Sur / Apple Silicon has not yet been merged to 3.8 and I believe @ambv has decided to release 3.8.7rc1 without it. So this IDLE 3.8 backport is not critical yet, but we should plan on getting it in soon.

@terryjreedy: Please replace # with GH- in the commit message next time. Thanks!
