Describe the bug

Programmatic slide control is not smooth, while navigating via built-in indicators is.

Steps to reproduce the bug

1. Go to https://codepen.io/gmw-web/pen/yLYqbqX?editors=1010

2. Click on the next/prev buttons in the slides, these trigger programmatic slide control.

3. See that the transition 'jumps' to somewhere halfway the animation.

4. Click the indicators below the next/prev buttons.

5. See that these trigger nice transitions.

Expected behavior

I would expect the programmatic slide control to trigger the same, smooth transitions as the indicators.

Additional context

I tried setting 'keys' on the individual slides, but this did not fix the issue.
