I recall discussion of this issue on the mailing list a number of times in the past, often involving more heat than light. I'd suggest searching the mailing list archives if this were possible. I had a quick look just now but I was only able to find this:
http://www.classiccmp.org/pipermail/cctalk/2021-May/058836.html I'm pretty sure I know why it's happening but I'm also pretty sure that if I try to explain, this will result in another long fruitless argument about it. I'll just say that I agree that gmail is causing it in this case and leave it at that. Regards, Peter Coghlan.
