This is an unfortunate side effect of the way we reimplemented the custom scrollbar functionality in the latest Skosmos release. When we switched away from the old and unmaintained mCustomScrollbar library, we had to also reimplement the centering of the hierarchy so that the currently selected concept is visible in the hierarchy when you open a concept page. I did that in PR #1372 (and tweaked in #1374) using the standard Element.scrollIntoView method. But this may scroll the entire page when the page is long enough, not just the hierarchy view which was intended.
