The bug
All blocks that can be waterlogged cannot be destroyed by flowing lava. This is certainly intended for water, but introduces illogical results in some cases when applied to lava. This is because plants that can be waterlogged and otherwise burnable blocks such as hanging roots, rails, signs and scaffolding can hold lava, at least momentarily.

h3. Expected results
Blocks that can be waterlogged and are flammable or plants should be destroyed by lava instead of being able to hold it.

I don't see an issue here when flowing lava flows into a water logged block it just creates cobblestone I don't see why they would need to be destroyed by lava
ampolive
This basically is just relevant for plants and flammable blocks actually, which should be destroyed by the lava. I don't know how to explain it exactly. I expect them to burn like, for example, redstone repeaters.
ampolive
This also has implications for the long run. For example, if redstone components are made waterloggable in the future, they will no longer be destroyed by lava, just like what happened to rails in 1.17 (MC-228125).
syarumi
I agree with your point of view, but seeing how almost all of the issues listed are WAI/WF, this would probably get resolved as WF as well, or even as FR. At least until there's a rework on how waterlogging works (if there's any) further waterlogged block additions would probably get used to stop flowing lava.
