Using a recent build of the 6.2.0 sandbox, I see an error screen when I switch between Wrangler connections, and sometimes when I delete a workspace. See attached screenshot.
In the browser console, I see:
Regression came from the update of React Router. There's a bug in react router where the underlying Route component always gets rerendered whenever there is a route change, even if the route doesn't match the current component's route. The fix is to remove the 404 catcher in the component, since the nonexisting route is already handled in the parent (DataPrepConnection) component.
