Fixes #3666
The sidebar appears above the content on screen sizes below 900px wide.
As we scroll down the page, sub-menus in the sidebar become active.
This pushes content down which deactivates the sub-menu, causing a loop.
An alternative solution would be to always display sub-navigation on screens below 900px, but this pushes content way down pages with many nav items, which is probably not ideal.
