Description of what you need help with:
How do I make sure that the scale animation tween’s starting point is on the left to right instead of centre and outwards (like in the gif attached)?

Steps to reproduce the behavior:

1. create a rectangle on one artboard, with 0px width
2. second artboard, with 30px width
3. create auto interaction from one to the next

Make the width and X animations have the same delay, duration and easing curve.
