Hi Joachim,
Thanks for your report! It would probably have been better to open a separate thread for this since your problem with the icon fonts has already been solved, and it is an entirely different problem (friendly hint for the future).
We had the same scrolling issue during testing and were sure we solved it. But as I can see in your videos, that’s not the case. So we will have to look at this again.
Unfortunately, I am not able to reproduce the issue, as you can see here: https://vimeo.com/695139849/061adeff80
But one thing is for sure: it’s not you 
Best regards,
