  1. Bug: The code in runner::Shared::handle_event does not properly enforce that ControlFlow::Exit is sticky. It only checks for self.is_closed() and does not check the actual user-assigned control out parameter. (I'm fixing this in a PR, just including this here for completeness.)
  2. After the event loop has ended, the canvas is not removed from the DOM or blanked and the event handlers are not removed.
