There are several issues that have to do with losing data by hitting the back button, anchor in overlay, and related. This is the place to link them all.

#1636992: form.js' formUpdated event is unreliable/incomplete
#153313: Form data is lost when using the browser's back button
#1542472: Clicking on multiple anchor links while in overlay causes a page refresh potentially causing form data to be lost
#655388: Many ways to lose data on form input in the overlay
#193799: Warn before losing changes (eg: blocks and menu admin pages)
#504378: Auto-save draggable forms

In contrib:
#1637404: Improve Drupal.behaviors.formUpdated

There might be some duplicates up there that need to be closed. These are old issues so I'm not quite comfortable closing everything for one.

The Drupal site I use most is d.o. I think we've all lost a long issue comment at some point.

Hence I agree this would indeed be valuable to have.
