Created attachment 32146 [details] tab selected on search results Are you search the catalog in the staff client you're presented with results, the results page used to keep the 'search the catalog' tab selected, but now it reverts back to 'check out' (now being in 3.16.4). I can't recreate in master, but don't see a bug that fixed this.
I can't reproduce this problem in master or 3.16.4. Please make sure there aren't any local customizations which might be causing the problem.
Can't recreate the problem either - closing WORKSFORME.
