Feedback needed when clicking on Persistence wizard → configure ASP gear button

When clicking on the configuration button on the Additional software section of the Persistence wizard, nothing happens for a while.

I clicked several times on it, and the menu opened several times too.

While fixing #15528 could also make this experience a little better, I think it would be good to have also a ‘spinner’ while you wait for the configuration window to open.
