When you place down big dripleaf and hanging roots underwater, they can be waterlogged. But the moment you place them, they aren't immediately waterlogged.
Step to Reproduce
Place down some big dripleaf in a river or an ocean.
--> ❌ It doesn't get immediately waterlogged.

Removed Spore Blossom since they no longer get waterlogged anymore
I'll keep this ticket open since hanging roots still not fixed yet.
Hanging roots unable to be waterlogged are tracked in MCPE-128957
They actually don't get waterlogged at all. Water flows through them, but they cannot coexist with a source.
