Debug tips:
 
    - Use `return;` incrementally to see if intermediate output is correct.
    - Use external IDE when editing script:
        - https://stackoverflow.com/questions/49509874/how-can-i-develop-my-userscript-in-my-favourite-ide-and-avoid-copy-pasting-it-to
            - Remember to still include @require and @grant in the tampermonkey script, not just the local script.

Reminder:
	GM_addStyle_from_file and GM_addStyle_from_string are currently being used to
  replace GM_addStyle.
 
  Currently checks if imagefaqs has already been loaded after clicking back button
  	See code immediately after print function.
 
  Relying on hacks:
  	// @grant       GM.xmlHttpRequest
    // @require     https://greasemonkey.github.io/gm4-polyfill/gm4-polyfill.js
 
  .embeddedImgAnchor > .embeddedImg (#video)   behave differently between firefox and chrome
    - In firefox, anchor's href is disabled while video is expanded.
      - Left-click does not shrink video, needed [Close Video]
 
    - In chrome:
      - Left-click will shrink video except when using video controls.
 
   May have to delay execution of entire script via setTimeout() to catch 
   particular end-user reported problems.
