KinematicBody2d move_and_slide function, The value returned by a collision at a particular location is not normal

[myhalibobo]

Godot version:3.1 beta4
Platform:win7
As shown in the figure below, now that my character is jumping up, and the character and platform are in this particular position, my velocity (-800,-484), at which point the character should have moved up.But move_and_slide() returns velocity(-800,0). This is incorrect.This should be a special case

Can't do anything without an actual project to test on.

Yeah, this seems like the same issue I just posted about in #30509, thanks for referencing it @myhalibobo. Thanks also for uploading the minimal example.

I can confirm #42574 fixes the issue (broken in 3.2.3.stable) in the 3.2 branch.
