I've got an upstream issue open for this and I recommend you submit this patch there so it can be incorporated into mypy. https://github.com/JukkaL/mypy/issues/653 I'll get this incorporated into the ebuild this weekend and if I don't see a pull request for this I'll add one but highly encourage you to provide the pull request since you've already taken the time to determine the patch.
Added this patch to the tree and mentioned it upstream. If there is anything else, let me know.
