render progress window doesn't show audio file progress

When excetuting a Render everything from in-to-out, with the setting to include audio when rendering turned on, the render window clearly and accurately shows video render progress, but with audio it's a blank progress bar   --- which can give the uncomfortable impression that nothing is happening.

Eventually it's done and the window closes.

But for long timelines this is a bit annoying.
