I was reading a story on CNN earlier today (from an HN) link. While reading, after scrolling through part of the story, I was prompted with an Android permissions dialogue asking for access to the device's microphone. This has become a common experience for me when browsing on mobile, but not on desktop browsers. What is going on on these pages such that they are asking for permission to record audio?
Here is the story I mentioned, though it is not unique in any way I can discern. https://edition.cnn.com/2019/01/10/business/costco-kirkland-signature-brand/index.html
