(V8preview) Cancel and go back to new live session

[megatux]

Problem

When running the installer I'd like to cancel it and continue with a new live session.(1)
I see the live session user login entry behind but it does not respond to interaction. It's odd to have it behind and not work. (2)

Proposal

Option to cancel the installation and use the current login entry gui to continue to a new live session

Prior Art (Optional)

No response

You can select the live session (Demo Mode) after selecting your language and keyboard layout:

It is a bug that the "Live session user" login card is shown behind the installer window (reported at elementary/greeter#732) and fixed in elementary/greeter#754.
