When the overlay covers a snippet, if that snippet is at the top of the page, the options at the top of the overlay are hidden. A system was made to make them change position in that case but this was broken by [1], leaving the toggling of a class for that case but without its related scss. This commit restores that scss and also improves the detection of that problematic case.
