It gets the controller name with step.class, and then FlowPolicy can get the key from the controller name.

is controller a Class or an instance?
If it's a Class we can do < to check subclass instead of iterating ancestors
Suggested change

That works! Cool syntax, if a bit opaque. Updated.

🛠 Summary of changes
This is an addition to #9589 to invalidate future steps when a user uses the back button and submits a previous step. We added the new call to
#updatefor welcome, agreement, link_sent, hybrid_handoff, how_to_verify, phone_question, and document_capture.Each step_info now has an undo_step parameter which is a proc that unsets whatever the current step sets.
FlowPolicy has a new method,
undo_steps_from!which recursively undoes all of the next steps after the current step.IdvStepConcern has a new helper method
clear_invalid_steps!that should be called at the beginning of the #update method of each IdV controller that allows the back button.📜 Testing Plan
