When using a block swapping technique to change a magma block water column to a soul sand water column, the bubbles generated take way too long to propagate up the column. This results in jerky bouncing up the column after swapping the bottom block to soul sand and keeps you going up long after the block has swapped back to magma.
This effect is not present in the Java edition.
The image attached hopefully clarifies what I mean with the block swapping.

What other basis do you have for saying that is too slow? It seems that the game "physics" is such that it takes some time for the bubbles to rise or descend after the block at the bottom is swapped. If it is just a request to make it faster, that would be a feature request, and so also invalid.
This is a duplicate of MCPE-51325.
If I remove the line that mentions the Java edition does this then count as a bug?
