Add additional Wizard tests for dynamic steps

[thatblindgeye]

Describe the enhancement or change
Followup to #10779 and #10748. Would be good to try and add tests for the behavior shown in these PRs to ensure as little breaks as possible in the future. The behavior includes dynamic steps working as intended (10748) as well as ensuring the Wizard doesn't unexpectedly reset (10779)

Is this request originating from a Red Hat product team? If so, which ones and is there any sort of deadline for this enhancement?

Any other information?
