@Gargron Looks like it has a few tabs. Preview shows the JSON stream, Headers, Cookies, Sizes, Timing and Security. That all seems to be working at the moment. My bet is that if I leave this pinned tab for some amount of time, Safari will eventually "shut it off"
@cdevroe If that's the case, I wouldn't know what to do about it. If the websocket connection fails, there's a retry mechanism, plus a polling fallback. If the browser kills the page so none of that happens that's outside my expertise 😦
