Issue description:
When using a spherical or cylindrical collider shape for the player, it seems to get stuck underneath a kinematicbody platform if the platform is descending. Check the attach video for demonstration:

Using a rectangle collision shape doesn't produce this problem. I've been trying to debug it for hours and using help, and I can't figure out why it's doing this, so I suspect it's a buggy behavior.

I tried using both move_and_slide and move_and_slide with snap and they have the same problem.
I also have issues with the snap when standing on top of the platform as the jump doesn't work, but haven't debugged it a lot.

Steps to reproduce:
Open the project and jump underneath the moving platform while it's descending. You will notice the player gets stuck under it during the duration of the descent.
