tests/rustdoc-gui/sidebar-modnav-position.goml

// Verifies that, when TOC is hidden, modnav is always in exactly the same spot
// This is driven by a reasonably common use case:
//
// - There are three or more items that might meet my needs.
// - I open the first one, decide it's not what I want, switch to the second one using the sidebar.
// - The second one also doesn't meet my needs, so I switch to the third.
// - The third also doesn't meet my needs, so...
//
// because the sibling module nav is in exactly the same place every time,
// it's very easy to find and switch between pages that way.
