No Vanilla Command Completion without op (but with Permission)

Hello.
I have given myself the vanilla command permission "minecraft.command.gamemode" so i can use the /gamemode command without being op and i can give these permission to no-op players. It works fine, i give the permission and then i can use the command. And when im op and deop myself i get the completion of the /gamemode command just fine. But when i leave the game, and join again (no op but with the permission) the gamemode command doesnt get completed and is in red colour (command does still work). My question ist: Is there a way that the commands get auto completed for the players that have the permission but are not op?
Thanks in advance
