While I was flying around in creative mode, I noticed an odd bug. Whenever I go down towards the ground (still flying), and when I hit the ground (still flying), I am unable to fly back up after hitting the ground while I am still in flying mode. I was flying under a structure, and I hit the ground, and I was unable to fly back up. I was also unable to go into walking mode. I had to teleport up to be able to fly properly.

I decided to test this bug out some more. While I was stuck to the ground in flying mode, I am unable to walk up stairs and slabs, which usually don't happen.

Please fix this.
