UserOptions menu
When placed inside a container with hidden overflow, and when the user options drawer is taller than this container, the user options drawer was cropped, making it impossible to access hidden actions.
To address this issue, the user options drawer is now placed inside a popover, which is now very largely supported. The popover naturally overflows in the above described scenario, and all actions are reachable.
If the popover API is not supported by the browser, the user options drawer defaults to the previous behavior.
