/**
* 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.
