Scrollbar doesn't update correctly when firing 'scrollTo' event

[riede]

It seams, that the scrollbar doesn't update correctly when using the SlimScrollEvent-Emitter with the type: 'scrollTo'. The content scrolls correctly (e.g. position y = 100) but the scrollbar stays on top. As soon as the scrollbar is moved just a little bit the content jumps back to top. Now, the content is based on the position of the scrollbar. Using the 'recalculate' event doesn't change anything.

I noticed a similar kind of issue. lets says I have 50 elements of 20 pixels each. and my container is 100px.
If I ask to scroll to the third item (scrollto (y: 60)) it will work. However if I ask to scroll to the 19th (scroll to y: 380) it just does not move.

So to make it work I had to use something like : Math.Min(contentHeight - scrollviewHeight, elementHieght)

More concrete example:

new SlimScrollEvent({
          type: 'scrollTo',
          y: Math.min(y, 24 * this.dataSource.data.length - 300),
          easing: 'inOutQuint',
          duration: 500,
        }),
