ajax/frames.php collected Frames.Id values from the event's rows and then
filtered with a FrameId IN (...) term, which FilterTerm translated to
Id IN (...). The search query had no EventId condition of its own. Once
the term matches on FrameId, which is only unique within an event, it
returns rows from every event, so the query is now anchored on the event
with the same WHERE EventId clause as the unfiltered list.
FilterTerm now maps FrameId to the FrameId column. The frames list
thumbnail links address the image by eid and fid instead of Frames.Id.
