Ok, that actually matches with what I saw. I SWEAR this was working for me at one point, but I have jumped back and forth in my git repo and am now having trouble finding at what point it actually functioned. I am wondering whether there is some combination of settings which make this bug pop which were committed to my repo, while the settings which do not make the bug appear are not.
But I think that you're onto something there in terms of the bug popping sometimes, while not others. I'll mess around with my settings a bit and see whether I can find anything there.
