Copper Chest rendering issue in water (Bedrock Preview)

Placing a Copper Chest in water causes visual glitches.
Some parts of the water do not render correctly around the chest, and weird triangle artifacts appear.

Steps to Reproduce:

1. Enter a world in Minecraft Bedrock Preview (with the Copper Chest feature enabled, if experimental).

2. Go into a water area (ex: ocean or lake).

3. Place a Copper Chest directly in the water block.

4. Look at it from different angles.

Expected Result:

The water should flow and render normally around the Copper Chest.

Actual Result:

• Water is not rendered properly near the chest.

• Triangle-shaped holes or visual artifacts appear.

• Some water faces are missing, creating a strange visual effect.

Notes:

• Only happens in the Preview version.

• Happens more when looking from the side or below.

• Does not affect gameplay, but it looks buggy.
