the dialog (and run limit checks) is installed by default on
checkboxes and selection menus, as it is already done for entry
boxes. Otherwise it is possible to make a selection (like changing
a device type) that invalidates the existing values, but if Apply
is hit immediately afterward, then no checks will be run and the
values may be used as-is even if invalid. This does not prohibit
the use of "add_dependency" to change the callback behavior.
