Well it's the same thing as how you can resume some downloads, but you
can't with others. It depends what the HTTP server is supporting.

At least, for non-live streams. It would make sense that live streams
are impossible to pause, but...

...yes quite possibly. It's not hard to think of how you could
implement pause for any sort of stream (just keep downloading!). But I
doubt any of our backends do this.
