However, I also understand that debugging a Windows only case might be beyond what we should invest for this particular patch. It's up to you, but to me it was weird.

I agree that this is a very curious situation, but I'm already too deep in the nested rabbit holes, so I don't feel that I can allocate time for this (especially since setting up a Windows environment would be lots of work for me).
