Placing a water bucket under a magma block or soul sand block and than replacing the water with powder snow will cause the water to disappear but it causes to make the bubble column to not get replaced. So even with leather boots you will get sunk through the powder snow whether it was a soul sand block underneath the snow or magma block. In the video I use a dispenser, but it still works by placing a powder snow in the side of a block.

Please do not fix this and instead make it a feature! This is a great way of making bubble elevators that look great. Once powder snow is dispensed or placed (using bucket) and washed away with water we can see a water less bubble elevator which works the same as bubble elevators inside water (moves items and players up and down), but look fantastic and are great for building in survival.
