Off-topic but Bloomberg.com related... How is the video element on this page so persistent? Using the latest Firefox, I have uBlock origin on with Javascript, pop-ups, and large media elements all disabled for this site. And yet, the small video player starts and follows me as I scroll the page and when I scroll back to the top, the large video player restarts.
