Show data and signals from inner/nested group elements

[mtravers]

Maybe I'm missing something, but it looks like the Vega Editor won't display data and signals for inner group elements. This would be very useful to me right now, I'm trying to debug a fairly complex visualization.

My suggestion is that these should be made available in the data viewer using standard dropdown, maybe using a dot notation or something (eg show them as group1.data, etc). Something similar for signals. An alternative would be to have some way of selecting a group element and have the debugger look at that, but that sounds more awkward.

Or, maybe there is some way to see this now and I am missing it, in which case the request is to make it more obvious.

Hm, this may duplicate #549

Ahh, good find. I did a quick search and didn't see that one. Yes, closing in favor of #549.

@mtravers for the time being, you can just move the signals to the top level to view/debug them and then move them back to their nested position once everything is working as required.
