Issue description

The vertical position of a character seems to have some kind of offset when two different animations are blended together inside an Animation Tree. This is not exclusive to the Blend3 node.

This behavior is not present in previous versions. I tested the same configuration using Godot 3.4 (beta 6).
I imported the character model using the .glb file from the TPS Demo. The problem is present in custom characters too.

Steps to reproduce

The following reproduction project showcases this behavior.

• Open the "TPS Demo Robot Scene"

Hi can I test this fix? The windows build under #54205 says it's expired...

@macryc Well, a while recently, I think the project manager was having some issues. So now I rebased #54205, can you checkout and build it, and do test?
