Strange slab placing behaviour

When holding "place" button and moving character or cursor, slabs should be placed in position as it starts.

How to reproduce: take a stack of slabs (any), place above you one slab and start moving character to the left or right (works with back and forth too) holding place button.

What should happen: slab blocks placed in same level and you don't angry

What happening in the game now: slab blocks places as they want depending on small cursor movements and you angry

Check video where I'm trying to place slabs in top block position in a row
