- Issue where idea was developed - https://www.drupal.org/node/1168246
- Issue where we are trying to look for an alternative polyfill - https://www.drupal.org/node/1839158
- This is the polyfill currently in use (it requires jQuery which D8 tries to avoid loading if there is an alternative, we no longer include it on every page by default)
- Details will be included in Firefox 49
