Feature request: Add setting to disable landing when touching down in creative fly

I am a bit annoyed in my building projects in Minecraft that I automatically stop flying when touching down in creative mode. I searched in the whole game and also in the internet but found no way of disabling that. I would like to have a setting that prevents the player in creative mode from landing just by touching down so you have to actively press double space to land.

I would have given this "bug report" the type "Improvement" if possible but it automatically jumps back to "Bug" when exiting the input field...
