What I expected to happen was...:
Bubble columns created by placing water above Magma Blocks or Soul Sand
would behave similarly everywhere.
What actually happened was...:
Bubble Columns do not form above y=63.
Steps to Reproduce:
1. Place a water source directly above a Magma Block below y=63
2. Place a water source directly above a Magma Block above y=63
3. Observe that the same setup of blocks behaves differently

Hi! I put this to 'invalid' since it's not the height/y level that gives the problem you describe. Bubble column generation depends on all the neighbor blocks (including corner neighbors). A bubble column can't for example generate if any of the neighbor blocks are air.
With this being said, I agree we should look into bubble column generation.
Ah, thanks for that hint 🙂
That would explain why my item elevator didn't work, it had air blocks on its corners. Simplifying bubble column generation by removing the dependency on neighbour blocks so they only require two water source blocks above might be a good idea.
I could produce bubble columns in naturally generated lakes above y=63, so my guess would be you just encountered the inconsistent behavior described in MC-125400.
