Sponges placed beside bubble columns become the water to become bugged

Sponges that absorb water with bubble columns absorb some water and leave bugged water where it didn’t absorb the water.

How to create it:

Place 1 block of soul sand.

Place 2 block high walls around the soul sand. It should be 2 blocks higher than the soul sand.

Place two water sources. 2 above the soul sand block.

Place a dried sponge block on the highest water source.

Outcome: It should make the lower water source bugged if you try doing basic actions in it like jumping.
