Survival inventory of creative leaves bug

What I expected was the leaves should show their real name in survival inventory of creative.

What actually happened was all the leaves in the survival inventory of creative(in multiplayer) were all oak leaves , e.g. Spruce leaves when placed in the survival inventory of creative turn their name into Oak leaves.

Steps to Reproduce:
1. Go into a server ,open the creative inventory , then go to the decorations
2. Select any leaf except for Oak, place the leaves you selected into the survival inventory (Creative one)
3. Close your inventory and open it again , the leaves will now turn into Oak leaves (Name only not the texture)
