✏️ Editing: visibility.fallback.js

// Add Page Visibility API support to old browsers by focus/blur hack.
//
// Include this script _before_ Visibility.js.
//
// Note, that this hack doesn’t correctly emulate Page Visibility API:
// when user change focus from browser to another window (browser and your
// page may stay visible), this hack will decide, that you page is hidden.
//
// For Firefox 5–9 it will be better to use MozVisibility hack without
// this issue. See <https://github.com/private-face/mozvisibility>.
