Wrong custom leaves data when placed on noteblock.

[Cryxow]

When placing custom leaves on a noteblock (vanilla & custom ItemsAdder blocks), the blockstate become the default one (distance: 1 | persistent: false)

The image above shows:

1. At the left of the noteblock; the custom leaves placed on ground.
2. At the right of the noteblock: the custom leaves placed on the noteblock.

What Minecraft version are you using? Also, can you send a video of what happens so it's easier to understand?

You can get the versions infos in my previous post for logs.
This problem occures on noteblocks, custom blocks using noteblock states, but fortunately not on logs.
