Which popup menus have titles that cannot be ignored, and why?

If we want some titles to behave in special ways, we could put a text
property on the title string to mark those titles that should get
special treatment.  That is better than removing the title, and
certainly better than removing it based on the frame type, because
then Lisp code which handles the menu keymaps will need to be prepared
to handle both kinds of menu keymaps, the ones with a title and ones
without it.  It is also against the documented practice.

So let's please reinstate the title, and use properties or some other
mechanism to mark the title strings that need special handling in some
circumstances.

Thanks.
