So IIUC 'mini-frame-frame' is always invisible in this scenario.

There is nothing else to focus here.

Is this "click" supposed to pop up the *Messages* buffer?

Not here.  But as I said above the original frame always has focus here.
I get

input-pending-p before: t
input-pending-p after:  t
input-pending-p before: nil
input-pending-p after:  nil
input-pending-p before: nil
input-pending-p after:  nil

with the *Messages* buffer focused before the second C-x C-x and the
same if I switch back to *scratch* where you say "Focus the original
frame".
