the use case is animating a button to change its size, left part corners are round, right part are not rounded until the animation finished, which looks ugly My solution is animating it from center so both sizes look same, probably not rounded, but would be great it they keep rounded during the animation

Animating from center may not be super helpful for this particular case, but could be useful to have. 🙂 Could you file a feature request please?

now it works perfectly 🙂
