Two or more KinematicBody2D on top of another KinematicBody2D makes the below one to move

[AttackButton]

Godot version:

Godot 3.2.2.stable

OS/device including version:

Windows 8.1

Issue description:

Two or more KinematicBody2D on top of another KinematicBody2D causes the one below to move and knock down the others.

What I found is that the size of the KinematicBody2D influences this.

Maybe related:

#27652
--> I tried to put infinite inertia = false in the move_and_slide_with_snap, although this argument is only for the RigidBody2D.

#36280

Steps to reproduce:
Place a KinematicBody2D on the floor with move_and_slide (or move_and_slide_with_snap) idle or moving, and make two others KinematicBody2D jump on top of the first one and keep moving at least one of them.

Minimal reproduction project:

Fixed by #36280. Just waiting for the merge to test it more.

Generally, issues shouldn't be closed until the fix has been merged. I'm reopening this and adding "Fixes #40006" to that PR.

I can confirm that this is broken in 3.2.3.stable and that #42574 fixes the issue for me on the 3.2 branch.
