To whoever edited my title: The bug report title is inaccurate. It's specifically about HSTS preloads, which is why my original title stated that instead of "gTLDs".
If OP thought it was misleading, then he was right to adjust it?
And that has had the effect that most of the conversation in this thread is about gTLDs instead of HSTS redirects, when the bug has nothing to do with the former (as noted by the comments where they specifically say that this does not happen to other gTLDs)
