Inventory Snaping Stops working

When you're inside the Manual Crating, and you try to move your items around, if you drag them into the middle of the inventory spaces, it stops snapping. It seems to fix itself when you leave and go back into it, nor does it seem like you lose anything.

Steps on how to recreate: https://www.youtube.com/watch?v=lkhiMbd8X_g
1. Drag an item in the middle of a slot in the inventory when you're in the Manual crafting
2. If it still snaps, try a couple more times. I had to do it like 4 times fast.
