There has been an ongoing issue with the /ability mayfly Command ever since the Release of the Education Edition /ability Command. When the person who isn't a host of the world and Isn't operator uses /ability mayfly true they take damage while in the sky and when they hover over water they drown. This can also be reproduced on a Realm with Education Toggle Enabled. Can you please look into this. I'd appreciate it. If you need video evidence, I'll try getting it with a friend. 

Thank you.
