go to Collection detail, tab Contents

there's a "Find conent" search bar, and a bar showing the per-type counts and allowing to filter by type: "Showing: All(23) Role(9) Module(3) Action(1) Filter(8) Test(2)"

Problem:
that "Showing:" line only shows correct counts when "All" is selected,
otherwise only the current type is counted, leaving other types at 0.

Solution:
filter by keyword first, then do the counting, then filter by type, then show the list,
(as opposed to filtering by both keyword and type before counting)
