Custom Leaf Decay broken on format version 1.20.50

Custom Tree leaf decay broken when set to format version 1.20.50 must revert all the way back to version 1.20.10 to work correctly.

I have been using this guide https://wiki.bedrock.dev/blocks/custom-trees.html#custom-log to make several custom trees which work after replacing block_property to block_state and format version 1.20.10 .

Setting format version to 1.20.50 breaks leaf decay. all the leaves decay even if they are grown from a sapling with logs blocks intact.
