Web viewer with form... how to avoid reloading page on Android when I click on a back button

I’ve a web viewer that include a form with more steps.
Now in the last step I ask to accept the privacy with the possibility by link to read it in an another page:

“I accept the privacy (link to the policy privacy) and bla bla bla”

The policy privacy has a javascript link to return back:

Now, on iOS (Safari) works good and when I click on the return back button, the page reopen in the same last step.
Instead on Android (Chrome) if I click on return back the page reopen but the form is reloaded from the start.

So, is there a way on Android/Chrome to avoid reloading pages when I click the back button?
