vertical scrolling on mobile devices triggers always the panleft or panright Event

[Killerbear]

Even if you set the direction to horizontal only.
If you press on the Hammer Element and scroll up or down, this motion triggers the on.("panleft") or on.("panright") event.
And after scrolling, the .on("panned") event does not get triggered.

you can test this in this example:

use browser in mobile mode or smartphone.
Pan up and down on the Element.

I can confirm that with v 2.0.8 and chrome mobile v70. Looks like it is a known issue - #1050
