Underwater ambience triggers based on camera position rather than player position

Underwater ambience can be triggered when only the camera is underwater (e.g., in third-person or with the /camera command), even if the player is not submerged.

Steps to Reproduce:

1. Enter a world with water.

2. Switch to third-person view or use the /camera command to position the camera underwater.

3. Listen to the underwater ambience starting even when the player’s head is not submerged.

Expected Result:

Ambience should only play when the player’s head (not the camera) is underwater.

Actual Result:

The ambience also plays if only the camera is underwater.
