BUG: space key play state changes not captured

[mountainash]

When the window is active, it's possible to use the "space bar" to toggle the play/pause state of the website - this isn't being captured by the app and the Menu title and Notifications will get out of sync.

I can give this one a go, seems fairly straight-forward.

Space bar is working to Play/Pause the audio, but the Notification are still not updated when used.
