Show action response data

Hi,

I would be nice if we could see action response data just like we can see form submission data.
That will keep us from switching from RDT to browser network console.

Thanks

The issue does not name any files, tests, or entry points. Start by locating the existing form submission data display in the devtools, then trace how action responses are received; done means response data is shown there without requiring the browser network console.
