Sure.  I did not yet file one because I'm not sure it is a bug.

I couldn't find a way.  But, apart from being usual, I think it is not
normal that a terminal frame becomes unusable as a consequence,
especially because I would not expect the behaviour to be undefined.

>I'd try "C-x 5 1" from the TTY frame first.

Tried.  But, as the docs say, that one deletes all other frames on the
same terminal, while I have a text and a graphical terminal.
