When I am on a Tab, and I reload the page, I should still be on that Tab

(Bug, Closed -> Fixed, Priority: Critical, Test Status: No automated tests yet , Reported By Justin du Coeur, )
Summary: Hit this while testing Roles, and it's annoying enough for me to call it a UX bug. Since we haven't been recording the current Tab in the URL, reloading causes us to go back to the default Tab.
