Bedrock Edition repost of MC-136695, but not exactly same.
Z-fighting when a chest lid intersects another chest under certain placement.
Steps to reproduce:
Build a setup like the picture attached.
Open the lower chest.
Observe the intersected part of the chest lid.
Observed results:
Z-fighting occurs when a chest lid intersects another chest.
Expected results:
Z-fighting shouldn't occur when a chest lid intersects another chest.
Notes:
The z-fighting will only occur when the chest placement is like the picture attached (facing the same direction or forming a L-shape with the upper chest facing the inside of the L). Other placements will not have the z-fighting issue.
