Even if erasing all the items is the intended behavior (I think
disabling all the items is less surprising at least for the tool-bar),
its timing is inconsistent. For example, if you replace Step 2 above
with (read-key) C-j, then menu-bar and tool-bar items don't disappear
immediately, but if you move the mouse pointer over a tool-bar item
and wait for a tooltip to be shown, then they will disappear.
