Xcode is scrolling my window when I press Command sometime, which makes my copy/paste tricky. How can I disable this?

This happens when:
- you use your 3 fingers to drag and do a selection
- then release your fingers in the small grey border ("sensible area" in capture)

It's just a bug. Just click to drag.
