VSE preview - how to preview other strips while editing meta strip

I’m working with the VSE in Blender 2.79b in Linux Mint 19 XFCE. I’ve got multiple meta strips, some of which contain image strips and some contain sound strips. The image strips have to sync with the sound strips.

When I tab into an image meta strip to edit it, the VSE preview window only plays the strips in that one meta strip. Any strips outside of that meta strip are not played, so I can’t hear the sound meta strips while editing an image meta strip.

Is there some way to force the VSE preview to play all meta strips while editing the strips in one of them?

Or do I have to ungroup the contents of an image meta strip to edit it in sync with a sound meta strip, and then regroup the image strips back into a meta strip again?
