Inconsistent pixels near light on the crafter's side

Steps to Reproduce:

1. Enable the 1.21 experiment

2. Place a crafter

3. Observe the texture near the lights on both sides when activated vs. deactivated

Observed Results:
The pixels on one side change when the crafter is activated, while the pixels on the other side do not. The pixels are inconsistent from each other when the crafter is deactivated, but become the same when the crafter is activated.

Expected Results:
Both sides should be consistent.

Screenshots/Videos attached: Yes. Side1 Deactivated.png is the only state in which the inconsistency arises.
