Created attachment 468324 [details] Test case reduction. Click link and check if audio plays. Expected behaviour: When the user clicks a link targeting an <iframe>, and the loaded document contains an <audio autoplay playsinline> element (or similar <video>), the audio/video will autoplay since it was loaded as the result of user input (clicking the link). Actual behaviour: When the user clicks such a link, the audio/video does not autoplay. Test case reduction attached.
