Applying a number variable to the width/height of an object with constrained proportions distorts the object, as it only overrides the one number but doesn’t update the proportions of the object. A common instance is when applying a variable to the size of an icon, it will distort the size until the variable is also applied to the other height/width.
Expected default behavior would be that when I apply a variable to the width/height of an object with constrained proportions, it resizes the corresponding shape based off the number of the variable just as if I typed the number in manually.
