emacs -Q. But I was confused about the scrollbar :-)

Under GNOME, I see truncation when the frame is too narrow. If I set
menu-bar-scrollbar-mode to 'always', I get a horizontal scrollbar when
the frame is too narrow. (I haven't retried KDE yet).

So itʼs all working fine, except for the visual glitch under KDE.

  ".mbtrunc  * { border-width: 1px; margin-top: -2px; margin-bottom: -2px; }\n" \

Iʼm thinking maybe that margin-bottom should be 0px or something? Iʼll
see if I can try that later.
