Fix configuration tree scrolling issues
closes frontend#500 (closed)
Goal of this MR:
- In a configuration's Platforms and Devices tab, the selected node information scrolls out of the viewport as the user scrolls down the page. When the user selects a node at the bottom of the tree, the node information is displayed outside the viewport. This MR solves the problem by making the node details "sticky".
Notice: currently as soon as the bottom of the tree is reached, the node information also scrolls up. To prevent this, we could increase the node tree's container height, but this would look somehow strange, too.
