Ok so I've added a codepen that hopefully shows the situation better.
The idea is that you scroll the page normally on your mobile device, but once you get to this section of red boxes, you can swipe them back and forth without the browser scroll moving at the same time.
So with allowNativeTouchScrolling set to true, as you swipe or drag those boxes the page scroll also moves up and down at the same time and I want to avoid that.
If you set allowNativeTouchScrolling to false it locks the slides as you swipe them as I want, but it kills your ability to scroll the page at all past that spot.
