 With the rule-based renderer, it is possible to have sets of rules that do
 not represent some features: if some feature are not matched by any rule
 (due to a filter or a scale criterion), they are not represented (which is
 normal), but their labels are still displayed, which is a bug. This
 affects the old labelling engine and Label-NG, in the map canvas and the
 map composer.

 The behavior should be the same as with the categorized renderer: if you
 delete one of the categories, the corresponding features are no longer
 represented AND the corresponding labels disappear.
