[Widgets] Short-circuit prerequisites feature because it's not working

This apparently wasn't well thought out. On important a file, it disables
the dependent property if the prerequisite is not satisfied. But it doesn't
change dynamically if the controlling property is changed. So it's better
just to not have the feature at all, for now.
