Lava falling property key not recognized

[BemusedLeader10]

The falling property key is used for lava springs, yet in the most recent update this is now no longer recognized by Spyglass

"state": {
  "Name": "minecraft:lava",
  "Properties": {
    "falling": "true"
  }
}

As far as I can tell, falling is not a block property of lava (it is a fluid property though). You cannot autocomplete it in /setblock and it isn't present in the data generated files.

Okay I see. The issue is actually that the spring feature type uses a fluid state rather than a block state.
