Survival mode Flying

While hollowing out an area for a cactus farm, I accidentally stumbled across this weird and wonderful glitch that allows you to fly in survival mode. It is not like in creative where you have ultimate control over every direction - it is just swim mode but in the air. If you hold forwards, sprint and jump at the same time while underwater you go into swim mode and rise up. If you are in water that flows one block underneath a roof of blocks, you carry on swimming out into the air. I have a screenshot of me first using it under the cactus farm if it is needed. There are conditions to fly though, the user must remain holding forwards, sprint and jump constantly for them to fly, and this only works if there are blocks above their head. Me and a couple others tested this on a creative world on Windows 10, Xbox and MCPE and it consistently works on all of them. As much as it would be cool for this to stay in the game, it really is gamebreaking and it is probably best to see the end of it. If you need any videos or the screenshot I mentioned earlier, please email me.

Thanks in advance
