A bug regarding particle effects that emit from painting corners.

What I expected to happen was:
The painting would hang on the block.

What happened was:
Particles emitted from the top right and bottom left corners.

Steps to reproduce:

• Place down a block.
• Place a painting on the block.
• Watch particles being emitted from the top right and bottom left corner.

I was experimenting with particle effects some hours ago, which includes this particle, but I switched off any contraption that might have caused this.

The particle effect is known as 'depthsuspend'.
