-// Compatibility with adblockplusui, to be removed when updating the dependency

[Sebastian Noack, 2016/02/02 10:39:54]

I am going to update adblockplusui and remove that code before landing this
patch.

-exports.isFrameWhitelisted = exports.checkWhitelisted;
 
 let getKey =
 /**
  * Gets the public key, previously recorded for the given page
  * and frame, to be considered for the $sitekey filter option.
  *
  * @param {Page}  page
  * @param {Frame} frame
  * @return {string}
