// I like to use this as a bookmarklet bound to a keyword. To create a
// bookmarklet, use the below code as the url for a bookmark, prefixed by
// `javascript:`.
//
// Go over all elements and hide any fixed/sticky ones in multiple ways so that
// they're less likely to get re-displayed.
//
// Also, set overflow to visible since scrolling is often in concert with
// showing popups disabled by setting overflow to hidden.
