ScrollView: fix cyclic Tab navigation

The ScrollView is not a control widget, which should be included in the
focus chain when the user presses the Tab key; instead, it's a container
and as such it should not interfere with the navigation.

We also modify TableView, because it derives from ScrollView but we
want to keep its current behavior.
