I don’t know if this contradicts your belief about mobile Safari, but it continues to bug me that browsing to CNN often (always?) stops whatever audio I already have running. I look forward to the day when all browsers prevent this kind of unwanted behaviour.
That should have stopped happening in iOS 11.4. If you’ve upgraded to-or-past that and you’re still seeing that happen, please let me know: email in profile or @jernoble on Twitter.
The iOS Twitter app does this all the time for me. I'll be listening to an audiobook and scrolling my Twitter feed, and the audiobook will pause as soon as a (muted!) video appears in my timeline. It's infuriating.
