Title: Fix banner images overlapping text in help tabs.

The pevious fix for the menu not being accessible made the banners use `position: absolute;` to get this working properly, but absolute also means, they don't move down with the rest of the page when the help tabs are expanded resulting in them overlapping text in the help tabs.
This fix makes the banner images temporarily invisible when the help tabs are open and brings them back when the help tabs are closed again.
