Detect navigation away from bug editing page

I was just writing up a separate bug and this happened. I accidentally hit alt+c instead of space. Jira loaded a new page, losing everything I had typed in.

Confluence has a feature to warn you if you're about to navigate away from a page that you've edited. Can we have something like this for Jira? If any fields have been modified, and the user clicks a link or uses a hotkey to navigate away, Jira should warn about it before letting the user continue.
