By clicking on the section header in a custom dashboard one can
navigate to the query of that section. In a dashboard space is limited
which is why the section queries are often limited by using the limit
and age operators so that a section cannot grow too big. Sometimes it
makes sense to drill down into a query and look at the complete query
result. This is why any limit operator is automatically removed when
drilling down into a section query. Do the same for the age operator
and remove it automatically when drilling down into a section query.
