Tweening issue when subscenes are used

Godot Version

v3.4.4.stable.official [419e713a2]

Question

I Have a simple scene with sprite as background.
BG is a parent to 2 Nodes.
Each of nodes has a child which is a custom scene.
Scene itself is type of Control (to achive clipping of children sprited) which contains a Tween and at least one sprite loaded throud gd script.
So what I would like to achive is animation running in every clipping area triggierd by button press.
What I got is animaton running only in one clipping area. Source code: GitHub - przybysh/GodotTweenClip

Ok. It can be closed. Issue casued by const qualifier which should not be used.
