Autosave and restore progress if user navigates away

Autosave and restore progress if the user navigates away from the feedback form

Environment: Production

Description of feature/enhancement

• Autosave progress periodically (potentially in local storage) and give users who navigated away but did not submit responses an option to restore their progress, especially for text editors.
• Maybe restore progress by default if users never submitted any responses.

Justification

• If we look at features in other apps, for example, creating GitHub issues itself, one simple navigation back and forward does not lead to any data loss.
• The issue occurred pretty frequently with me as I ended up navigating away by mistake (going back by swiping on the touchpad) multiple times and lost progress.
