Prevent accidental navigation on public form page

[wanlingt]

Is your feature request related to a problem? Please describe.
If a user on the public form page accidentally navigates back or forwards on their browser (e.g. by swiping the trackpad) and returns to the public form page, they lose all information that they've already filled in

Describe the solution you'd like
Possible solution: A confirmation modal pops up to ask if they're sure they want to navigate away from the page

Another potential solution could be save as draft. That will be prioritized later.

This issue should not be there now because we have implemented back button and breadcrumbs.

@amitogp i don't think this actually done, since this is referring to public form respondents navigating away from the public form page

Aahh got it.. it's for respondents. Reopening now.
