Issue description:
Kinematic body slides off slopes that is supposed to snap to when landing.

Steps to reproduce:
use this script on a kinematic body 2d with any collider.
jump on a slope >=45 deg

extends KinematicBody2D

# Declare member variables here. Examples:
# var a = 2
# var b = "text"

export var gravity: = Vector2(0,4)
export var moving_vel: = Vector2(8,0)
export var jumping_vel: = -Vector2(0,50)

var _totalVel: Vector2
var _vel_remainder: Vector2 = Vector2.ZERO

# Called when the node enters the scene tree for the first time.
func _ready():
#	jumping_vel-=gravity
	print(jumping_vel)
	pass # Replace with function body.

# Called every frame. 'delta' is the elapsed time since the previous frame.
func _physics_process(delta):
	var _snapVec = Vector2(0,64)	
	_totalVel.x = 0
	if !is_on_floor():
		_totalVel += gravity
	else:
		_totalVel.y = 0
		_totalVel += jumping_vel * int(Input.is_action_just_pressed("ui_up"))
		_snapVec -= int(Input.is_action_just_pressed("ui_up"))*_snapVec
	_totalVel += moving_vel * (-int(Input.is_action_pressed("ui_left")) + int(Input.is_action_pressed("ui_right")))
	if (_totalVel.y > 0):
		print(_totalVel)
	if(!is_on_floor()):
		print(is_on_floor())
	move_and_slide_with_snap(_totalVel*64,_snapVec,Vector2(0,-1),false,4,45.0)

This issue #26274 seems close to mine but the effects are different.
Please move if needed

Soo the floor angle is in radians not degrees. Also if you want to prevent sliding, pass true to stop on slope.

This tweak fixes the issue:
move_and_slide_with_snap(_totalVel*64,_snapVec,Vector2(0,-1),true,4,0.8)
