Respawn anchors destroy blocks when detonated underwater

The bug

When a respawn anchor is placed underwater either in the overworld or the end, and it is used and thus explodes, the explosion will break blocks, even though the block is underwater. As other explosives do nothing underwater, I would assume that this is unintentional.

To reproduce

1. Place the respawn anchor underwater

2. Charge it with glowstone

3. Use it
