The problem is not setting both height and width, the problem is
changing frames on a TTY after that.

What a strange thing to do!  Out of curiosity: why did you need to do
something like that?  What did you expect to happen when you change
the size of a TTY frame?

The 5th character exceeds the 9-character width of the frame you set
inside with-selected-frame.

Fixed in revision 117327 on the emacs-24 branch.
