In the Frame Debugger, how do you see what is in a Static or Dynamic Batch?

The documentation makes it sound like you should be able to see what all is in a batch in the Frame Debugger by clicking on the "Static Batch" or "Dynamic Batch" event, but it doesn't say how. If I click on one, nothing is drawn in the Preview window - all I see are the number of vertices and indices, and some shader data. Nothing in the hierarchy is highlighted, nothing in the game view is, and ShaderProperties shows just that, the names of textures and Vectors and whatnot.

I'm working on a complicated VR app, targeting 90fps of course, so knowing what exactly is being batched without doing tons of experiments would be quite useful.
