Describe the Bug

When standing in a corner of a train that is positioned in the beginning of a slope, the player levitates for no apparent reason without pressing any key. Even crowching can't get the player down, only moving away from said corner.

Reproduction Steps

1. Build a train car: It should have two bogeys and five blocks in between. On one side (from now on called "front"), add controlls in both directions. When facing towards the front on the left side, add a block next to the first block after the bogey and put an open trapdoor in front of it. Place a block right of the back bogey and add walls another block to the right as well as on the back side of the block you just placed. The train should look like the one in the screenshot. Glue it all together and assemble it.
   

2. On the end of the track, go from the center of the track 8 blocks to the right and 8 blocks ahead. Put a pillar of three blocks there and place a rail on top perpendicular to the other rails. Link the two rails whilst pressing the "Ctrl" key (or whichever key you use to create nicely bent curves)
   

3. Next to the last piece of straight rail, tower up two blocks and build one towards the center of the rail. Place an open trapdoor ond the side of the curve of the contraption you just built.
   

4. Place the train such that the two trapdoors touch.
   

5. Walk against the corner inn the back of the train, then release all movement keys.

6. You start to slowly levitate.

Note that the trapdoors and are only there to allow to place the train at the right position in the slope

Expected Result

The player should not levitate
