My goal with this issue is to simply unblock the use of docstrings in Python tests. I believe with the work above and the proposed published post, I've accomplished that goal. I've already spent more time than I'd hoped on this issue and would like to resolve it at its original scope.

I do see how this issue reveals some deficiencies with the current UI/UX, and I'd welcome a separate feature request to address those deficiencies. I'll even help draft the bug report on request.
