Just updated to 12.110.0 and now when I click "pop out" on any window I get "No page corresponding to this URL could be found"
Also a bunch of statistics seem to have gone missing in the dashboard. Yes I did run migrate.
EDIT: Most statistics seem to be back, less info in the dashboard than there used to be, but ok fine, that's progress. Pop-out windows still bugged. Cleaned browser cache, tried other browsers, doesn't work. Pop out urls end in ?zen and don't load.
