Clicking on "More" in the Runtime libary section also scrolls. My more button was fully visible, only the title of the section was partially hidden. It scrolled (escaped from under my mouse) quite a big distance, such that Runtime section appeared in the middle of the editor (verticaly). I do not think, the scrolling is needed at all for the buttons, as clicking these buttons is taking me to another editor or page.
Scrolling is needed when focus moves to the control that is currently not showing in the scrolled composite. The support should scroll the client to reveal the control in focus. That means that controls that are already visible should be left alone, which is clearly not the case. We know about the problem in the 'reveal' method and are trying to fix.
