"Present a warning dialog when ... tab is in Running State"?

Apologies if this is not the proper place for this question: is it possible to implement a fourth setting that would mean "present a warning dialog when closing multiple tabs/panes at once AND at least one background tab is in Running State"?

Moved this over here. Honestly, I think this should just be its own warning toggle:
`warning.closeRunningTab`: `true|false`

That way, if you're _ever_ closing a tab that's running (or if you close multiple tabs at once, and one of them is running), you'll get the dialog.

I'm sure there's other states we'd be interested in this scenario (i.e. progress, etc).
