~~Huh, maybe the fix of MC-1809 has gone too far...~~

Do you have the 'vanilla' datapack disabled? That's what caused it for me in the late 17wXXx snapshots.

Edit: The cause of this is because the vanilla data pack adds a block tag that tells leaves they are by a log. The minecraft:log tag. The leaves search for a block from this tag to check if they should decay. When vanilla is disabled, there is no block tag, so the leaves say "Well, I will decay then." And this happens.
