move_and_slide makes bodies overlap

[Markaroninoranor]

Godot version:
First appeared in Godot 3.1 Beta 6, still the same on Godot 3 RC 3

OS/device including version:
Arch Linux

Issue description:
When I'm using the move_and_slide function with changing linear_velocity parameter, the body tends to go "inside" of other bodies in an unexpected manner. It never happened to me in Godot versions before Beta 6.

Steps to reproduce:
Use keys WSAD to control player. When the player lands on the ground press S to increase velocity.y, player should then fall a bit into the ground.

Minimal reproduction project:
move_and_slide_minimal.zip

Also having this issue, game physics worked fine on 3.0.6 and 3.1 beta 5, doesn't work on 3.1 stable or any later beta versions. Any updates on this?

Maybe related with this bug also ? Please take a look at 2D and 3D Kinematic overlapping issues here also. #27652

Doesn't seem reproducible in the current master branch, it must have been fixed since then.
