🍕 Delicious auto scrolling #349

Previously when a user picked up a draggable item that was near the edge of a scrollable area it could trigger a large and jarring auto scroll. We have created a solution that gets around this problem in a really elegant way.

I have created a video which goes over what we did in a bit of detail 📺

A big thank you to @ajaymathur and @jjcm for their huge help with this one
