Add capturing event listeners to the KeyboardShortcut library

[roryabraham]

Shoutout to @HorusGoul for figuring this out. In the slack thread you made it sound like we should always have capturing event listeners, unless we specifically want to enable bubbling for certain events. I wasn't sure of the potential side-effects of preventing event bubbling by default, so I opted for the minimum change that resolves the current issue. Feel free to follow-up with any thoughts regarding other events which should not bubble.

TBH I'm not 100% clear on why this fixes the linked issue, but shoutout to @HorusGoul for finding this! It works! 🎉

Not sure at the time but it could have side effects. Like when we want to stop propagation for all listeners.

<document> <---------- don't want it to know
   <div> <------------- don't want it to know
      <div> <-------- event Source.

capturing will fail this scenario.
