/**

 * Bug 1934908 - www.cbsnews.com - Override UA on Android to use JS HLS player

 * Spoofing as Chrome forces the site’s HLS.js player. Native HLS is controlled

 * by media.hls.enabled, which defaults to false. When false, video doesn't

 * play back at all. When true, video will play back for a minute or two before

 * stopping. With this override video playback works consistently regardless of

 * how media.hls.enabled is configured.
