fix: prevent the escape key from minimizing Safari (#265)

* fix: prevent the escape key from minimizing Safari

Safari uses the escape key as a shortcut for exiting full screen.
Stopping propagation is _not_ enough to prevent this behaviour. Use
`preventDefault` instead of `stopPropagation` to avoid messing with the
users' browser experience.

Closes: #264

* fix: stop propagation in addition to preventing default
