Check if closed before closing.

If for whatever reason the close method is called on a remodal after it has already been closed. The closing event will trigger and wait for the closed event to fire, but as its already closed, this will never happen. So it will be stuck in the "closing" event state and will no longer work if a user tries to open it again.

You can test this if you call the clode method inside a timeout function on the "opened" event, then close the modal manually before the timer function executes its function. One the timeout functions runs you can no longer open the modal at all.
