Set focus on the form heading when the user goes to the previous or next steps in the form

[obliviga]

Description

Focus needs to be managed when the user goes to the previous or next steps in any given form. Currently, focus is set on the body element by default, which is not user friendly. Instead, focus should be set at the top of the form, which is the heading. This helps the user understand where on the page they are in relation to all content and keep their understanding of the flow of the form in tact.
