Event callbacks are catching and ignoring my errors

[ffxsam]

Expected Behavior

If I make mistakes in my own code (within the event callbacks), I'd expect to see an error in my console.

Actual Behavior

I see no errors because the processData function is catching & ignoring errors.

Steps to Reproduce

player.on('play', () => {
  throw new Error('unseen error');
});

I'm not sure what options are available to us here. We need to catch the error when running the callbacks, or subsequent ones will not run. I don't think we can re-dispatch that event on window like what would happen with an EventTarget. Maybe we can extend EventTarget and use that mechanism instead. Not sure when we'd be able to do that work, though.

I'm open to other ideas too.
