When there is glow lichen next to flowing water it makes that water somehow transparent. Also water corners are not well bounded and make weird straight line on each side. Everything can be seen in attached videos for both versions of the game. In Java Edition everything works as it should.

Step to Reproduce

1. In Java & Bedrock version create new world, place glow lichen vertically on some block.
2. Take a bucket of water and place it next to that block with glow lichen, so water flows downwards.
3. Observe the transparent visual glitch that occurs on the water.

Observed Result
Glow lichen makes flowing water transparent when placed next to it.

Expected Result
Glow lichen shouldn't make water transparent when placed next to it.
