-e: when you rename a long exposed parameter to something short the menu snaps to the left instead of the right ends up away from the rest of the UI. after reopening it is at the correct place again.

-repro:
--create new mixer
--expose a parameter
--rename the parameter to something very long
--no rename the parameter to something short
--NOTICE the parameter menu snaps to the left
--reopen parameter menu to make it show up in the right place again
