That's not what I understood of reading the posting guidelines [0] and especially "Otherwise please use the original title, unless it is misleading or linkbait."
If OP thought it was misleading, then he was right to adjust it?
Indeed the "title" of the original page is misleading (because the original bug submitter thought it was one issue, but was really another).
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)
If OP thought it was misleading, then he was right to adjust it?
