Toasts occassionally double-fire

[seinwave]

This is because the connect() method in the toast_controller is firing twice. For somewhat mysterious reasons. You have tried:

❌ Catching the turbo preview (none of the connections are from turbo previews!)
❌ Debouncing the addToast method (didn't work, because we're firing the connect() method in a different instance each time)
❌ Counting / restricting the number of flash requests (there's only one!)

Something else to try:

• Looking for an existing instance of the toast_controller, and not firing connect() if it already exists. Not sure how to do it.
