Comment:

 This is reproducible on Standard by disabling Noscript's media capability
 for Default.

 Hi ma1, is this a known bug? I don't see any obvious open issues for it.
 It's an embedded third-party iframe from youtube. Media cap is disabled.
 The video element shows the play button. After clicking the element so the
 video begins, Noscript shows click-to-play. After clicking the element
 again, Noscript prompts for allowing media. After allowing media the video
 shows a spinning animation and then returns to showing the play element.
