The game crashes when a piston pushes a water cauldron with the "Improved Transparency" option enabled

I’m unable to reproduce this issue

Can reproduce, caused by Improved transparency setting.

Steps to Reproduce:

1. Enable Improved Transparency

2. Place a cauldron, fill it with water

3. Place a sticky piston with the sticky face next to the cauldron.

4. Place a lever next to the piston.

5. Activate the lever.

Observed Result:

The game crashed: render frame
Error: java.lang.IllegalStateException: Render type solid_moving_block does not have OIT pipelines set up.

Game crashes.

Can confirm, after following @TheMightyDark’s steps, the game crashes with the following crash logs:
