Most times, but not always. But it's better now at remembering what you typed if you accidentally navigate back then hit forward. I imagine in some situations I could accidentally lose form or input focus, hit backspace, and then lose everything. This could be an app that manually captures key presses with JavaScript rather than a regular input.

Sounds like an app like that should implement some kind of 'are you sure' using onbeforeunload. There are plenty of ways to navigate away from the current page (or close the tab/window) besides hitting backspace.
