RayShape using move_and_slide or move_and_slide_with_snap with snap argument == (0,0) snaps into a vertical wall

[AttackButton]

Godot version:
3.1 Beta 8

Issue description:
With the move_and_slide or the move_and_slide_with_snap with snap argument == Vector2(0,0) and if a rayShape collides with a vertical wall it snaps to the platformer above.

The rayShape behaviour:

The expected:

The expected behavior of rayShape when the move_and_slide_with_snap snap argument is (0,0) or using the move_and_slide and the character is colliding with a vertical wall would not to leaning the wall but without the snap? Or maybe ignore the vertical wall?

Note: it is working perfectly with slopes.

Steps to reproduce:

Create an platformer game and add a collisionShape2D with a rayShape shape to kinematic body for the slopes.
Use the move_and_slide or the move_and_slide_with_snap with snap argument == (0,0).
Jump or move in a vertical wall direction.
