Minecart with command block can be destroyed in survival/adventure mode

The bug

Based on MC-11765 you would expect that players in survival or adventure mode are unable to destroy command_block_minecart. However, this is not the case, they can destroy it like normal minecarts except only a minecart drops.

Expected behaviour

All command_block_minecart are invulnerable (?) or at least resistant against damage dealt by players in survival or adventure mode.
