A KinematicBody2D can push another KinematicBody2D through a moving one-way collision platform

[AttackButton]

Godot version:

Godot 3.2.3-stable

OS/device including version:

Windows 8, Geforce 840M, GLES3

Issue description:

A KB2D jumping over another KB2D that is on a moving platform with one-way collision as true causes the latter KB2D to falls off from the platform.

** The moving platform is also a KB2D.

** I confirm that #42574 does not fix this bug.

The moving platform with one-way collision as true:
On the right side the KB2D does not fall, cause it is over a StaticBody2D platform, even with one-way collision as true.

The moving platform with one-way collision as false:

Steps to reproduce:
Create a moving platform with one-way collision as true, put a KB2D to jump over another KB2D on that moving platform.

Perhaps related to this. If you step on another KB2D on a side-moving platform, they will slide. In 3.2, they both moved along with the platform.
