Jungle leaves decay into oak tree's drops

CANNOT REPRODUCE ANYMORE

• Short description of the issue

Jungle leaves decay into oak tree's drops. Other trees not affected.

• Steps to reproduce the issue

I haven’t tested with player-grown trees, but you can create a single biome world with jungle and fill the logs with air:

/fill @a ~~~ ~20 ~-20 ~20 minecraft:air replace minecraft:jungle_log

• Expected result

Jungle saplings and sticks, you can get them by breaking the leaves

• Actual result

Sticks, apples and oak saplings
