Prevent form validation when using Previous button?

Problem/Motivation

When using the Previous button to move back in the form steps, fields marked as required are validated.
This prevents a user from moving backwards in the form if they do not provide values for the fields on the current step.

Steps to reproduce

  1. Add steps to a form display as per module documentation.
  2. Set a field on a later step in the form to required.
  3. Attempt to use the Previous button. The required field will set a form error.

Proposed resolution

Somehow allow for users to move backwards in the form using the Previous button even if required fields on the current step are not complete.

I'm not sure how this might be accomplished. I've tried setting limit_validation_errors in a form alter to a few places and it doesn't seem to take. Would something like this even be possible?

    Agreed. It would be useful. Change committed to look for form errors after the form validation has completed and only when the previous button is the triggering element. Detected form errors are cleared and the value is either reset to empty (null) or back to the original value (when editing). Thus only resetting invalid values whilst preserving valid values when using the previous button.

    I just tested the new version and it works perfectly. Required fields not filled when using previous do not stop the user, but fields that have been set retain their value when returning to that step.

    Excelsior!!
