Hello, i would like to report a bug i found in the recent pre-release when in swimming animation if you aproach land and jump on it you stay in the swimming animation and you can jump using the water mechanics and such and the only way to revert to normal is to get in the water and cancel the swimming animation or reconnect,Here is a video of how i did it https://youtu.be/pV4hwfZq9I0 i also provided a couple of screenshots
Environment
Im using WIndows 10
java version: version 8 update 171 (Build 1.8.0_171-b11)
this bug is done by other players too so it is not a system specific
it was done in a multiplayer world
