But this would mean that if a scroll animation is in progress and the user clicks e.g. a scroll top button that would just not register. I think the current behaviour, while not ideal, is definitely more correct than with your changes.

You can also see it in the web demo. I put the scroll animation duration to 1s to make it easy to see.
With master if I quickly click scroll down and then scroll up while it hasn't completed the animation yet it will scroll back up:

With your changes it will not scroll back up:
