Steps to Reproduce:

1. Place water on the ground;
2. Surround it with moss blocks.

Observed Results:
The water gets blocked and doesn't flow.

Expected Results:
The water flows through the blocks.

Screenshots/Videos attached: Yes

Notes: Even though water flows through moss blocks, they can't be waterlogged (coexist with a water source).

Original Description:

So, whenever I try to replace a block next to water with a moss block, the water flow starts to flow in the direction of the moss block, and the water bucket does not fix it. I can't provide any screenshot or video, because I am typing this on computer, and my platform is on Xbox.
