Control nodes get resized randomly when using AnimationPlayer and instancing

Issue description

When a AnimationPlayer is used to animate Control based nodes in a scene that is instanced, and the instanced scene is run, the Control node gets resized and moved, both in the instanced and in the original scene. The rect_size property gets doubled, and if I don't fix it and open it a few more times, it gets tripled, quadrupled etc., and sometimes this happens with rect_position too. The animation player does not have to contain the property which gets changed, I had the rect_position animated, and the rect_size was changed. It seems to only happen when using instancing, as I already mentioned.

Steps to reproduce

• Open included project
• Open BaseScene.tscn, there is a Panel at the bottom exactly as wide as the window
• Open InstancedScene.tscn, play scene, Panel should be missing
• Close game
• Click on the BaseScene tab, Panel gets moved and resized
• If the InstancedScene is run more times the Panel gets bigger and bigger

Also having this issue in 3.4.3 stable, quite problematic. Anybody have a good workaround?

EDIT : worked around by constantly setting rect_size of node being animated to the rect_size of a parent control that is not being animated.

That's what I did too, setting the size and position back in code. Still pretty annoying.

I'm having this same issue in Godot 3.5.2
