Disabling user interaction during animation

While running the slide animations with Simulator > Debug > Slow Animations enabled, I realised that the buttons are interactive. So we can tap ‘Next Question’ while the next question is coming in. A couple of quick taps and the next question starts to disappear during the slide or after the animation is finished.

I think we should disable user interaction while the animation is in progress. This should be a good default practice for most animations like this.
