Description
Expected behavior
When players are granted this permission, I expected that they would be able to open the interface for Command Blocks.
Observed/Actual behavior
When I pressed the use key, nothing happened despite having the "minecraft.commandblock" permission. The block can still be broken, however.
Steps/models to reproduce
To reproduce this, make sure that you have the "minecraft.commandblock" permission and don't have operator privileges. Try pressing the use key on a Command Block. Nothing will happen.

Research direction
Start by reproducing the command block interaction with a non-operator who has the minecraft.commandblock permission, then trace the permission check for opening command blocks and command block minecarts. Done means both interfaces open for permissioned players while players without the permission remain unable to open them.
