When saving to mhtml format, only the first save is the correct suffix, and subsequent save file suffix is wrong (becomes incorrect html format).

@TheShaunSawThanks for your response.The bug has been fed back a long time ago, but the situation has not improved, the bug is easy to reproduce and only needs to save the page as mhtml format more than twice. Edge Dev 86.0.594.1 and Edge 84.0.522.52 both have this bug.
