Interestingly, the Web Developer Tools menu does change the font size,
e.g. press F12 and C-+ and the font size of the Web Developer Tools menu
changes too.

Only the widget toolkit based menu does not change the font size.

I never understood why web browsers depend on widget toolkits
when they already implement everything needed
and do not adhere to "native" look-and-feel anyway.
Widget toolkits impose such inflexible restrictions
and import annoying problems.

Like somebody recently complained about 2sec delay when opening Emacs menu.
tmm-menubar does not solve it fully, because in gui emacs,
menu invocations by mouse are hardcoded to use toolkit based menu.
