I just learned about the variable x-gtk-whole-detached-tool-bar; when
this is non-nil, the detached tool bar is displayed just as when not
detached, i.e., horizontally, full-size, and fully expanded.  With this
detached tool bar, tool tips do pop up when the mouse pointer moves over
tool bar buttons, just as with the non-detached tool bar.  So it is only
with the vertically expanded detached tool bar (which has smaller
buttons), i.e., with the default nil setting of
x-gtk-whole-detached-tool-bar, that the tool tips are missing.
