Big Spruce Trees don't generate in Groves

Isn't this just a duplicate of MC-236630? That one was closed as invalid with no reason. The fact that spruce trees don't generate is a bug, but the "big spruce trees" thing on the changelog wasn't literally meaning giant spruce trees.

Well, doesn't matter if this one stays open anyways.

I think this one is more detailed than the other report

I think this is because trees cannot generate on snow blocks - I created a ticket for inability to place vegetation on snow blocks - MC-237058, because it might be the cause of this bug.

This bug was not fully fixed correctly, as there are still too few trees, especially on steep slopes. The Bedrock generation for the trees does this correctly, note that the slops in the Bedrock screenshot of the same seed have trees generating correctly on the sides of the mountains. https://bugs.mojang.com/browse/MCPE-141577?jql=text%20~%20%22groves%22

Here is a screenshot from the latest Snapshot and latest Beta, showing Java's still broken generation:

@unknown you might want to create a new ticket for that as this ticket specifically pointing out about spruce trees in groves don't generate at all. Whereas, your report is about spruce trees generates less than the bedrock version.
