Selecting one of the last items in the editor changes the position
When selecting (or validating the previous item and going to the next) an item that is near the end of the list in the editor, the scrollbar goes back a little, so the item is now hidden.
Possible cause: when a user selects another item, the edition zone is cleared and replaced by a new one; this means the zone disappears shortly, the list is expanded to the bottom of the window, and when the zone is created again, the list is contracted to its original size, showing the same first element as when it was expanded. Replacing one element at a time instead of the whole zone at once might solve that issue.
