/worldborder get command will not display a success message when run in a command block

Well, this is only partially true, it will display in the previous output box, but not in the player's chat.

In case your wondering, my commandBlockOutput gamerule was set to true.

UPDATE: this also doesn't work with the /execute command which makes the bug more puzzling as /execute is meant to run the command as if it had been run by the entity specified in the /execute <playername>
