When I user start writing a reply to an existing post it can accidentally type ALT+LEFT ARROW, which is the shortcut for "go back" button (at least of Firefox and Chrome). If this happens after the user wrote part of his post, and then he clicks in the Forward button to go back to the page he was editing, the content will be missing and the user will need to write everything again.

This problem doesn't happens in the normal mediawiki editbox and shouldn't happen in LQT either.
