* listen for both `mousedown` and `pointerdown` events
This is necessary for calculating the target where the focus will
eventually move to. Some other libraries will use an
`event.preventDefault()` and if we are not listening for all "down"
events then we might not capture the necessary target.
We already tried to ensure this was always captured by using the
`capture` phase of the event but that's not enough.
This change won't be enough on its own, but this will improve the
experience with certain 3rd party libraries already.
* refactor one-liners
* listen for `touchend` event to improve "outside click" on mobile devices
* update changelog
