Bug

Describe your proposal.
I would like to use a WIzard with some steps that are required, like the doc.
However, if I fill the required field > go to the next step > go back by using the fd-wizard-progress-bar > delete data in required field
I can still go to the next step with the fd-wizard-progress-bar but it's not possible because required field is empty and the button next is disabled.

Which versions of Angular and Fundamental Library for Angular are affected? Please, specify the exact version. (If this is a feature request, use current version.)
Angular : 18.2.0
