Describe the bug

During the picking up of an item (that is 3D, ie a block, bed) the shading appears to be applied wrong during the pickup squish then flip as soon as the pickup squish is finished.
For all I know it may occur on 2D items as well since they're extruded, but I cannot tell.

Steps to reproduce

1. Pick up a 3D item
2. Observer shading (full blocks are more noticeable)
