Noticed what looks to be some kind of rendering error when a wall is placed underwater.
On either side of the wall, there is water flowing downwards in the spots that would normally be the sides of a full sized block.

Thank you for your report!
However, this issue has been closed as Working as Intended.
Non-solid blocks such as this need to be waterlogged by using a water bucket on them. This behavior is consistent between Bedrock Edition and Java Edition.

You need to place water directly onto the wall to waterlog it.
