This is not a bug, this is the intented behavior of that feature, which 
was discussed on emacs-devel and in bug#51377.

But in commit 997ca88ef44 the word "last" disappeared in the explanation 
of the meaning of the symbol 'kill-terminal': "when the last frame is 
being closed" became "when the terminal is killed".  Hence the confusion.

I attached a patch which preserves the intended behavior of that feature, 
and adds a fourth possible behavior, the one Jim now wants.
