I have run into this problem too... So I decided to make a command block contraption to test it out! To use it, follow these instructions: 1) Copy the command from this link: pastebin.com/b87iGSzp 2) Get a command block. (Use the command "/give @p command_block") 3) Paste the text into the command block and change "Needs Redstone" to "Always Active". 4) Activate the machine by flicking the lever. The redstone lamp should turn on. 5) You should have been given a splash potion. Throw it to levitate, and hold down right-click to fly higher. 6) Use the command "/gamemode 0" to enter survival mode, and throw the potion to demonstrate how levitation doesn't negate fall damage. 7) Once you're done, flick the lever again do disable the contraption. The redstone lamp should turn off.
