Bug

Moving blocks with a Piston causes the moved block to no longer have any ambient occlusion, causing it to be flashing bright. This is probably due to the new changes with ambient occlusion that happened around 1.21.40/1.21.50.

Steps to reproduce

1. Place a Piston with a block in front of it
2. Power the Piston with a button
3. Look at the moving block

Expected result

The moving block keep its ambient occlusion, and does not flash while moving

Observed result

The moving block loses its ambient occlusion until it is moved into place, causing it to flash briefly. See the Moving block no ambient occlusion.mp4
