Drag and drop a tab to another position on the tab bar while holding ctrl. (Might be command or whatever on Mac?). No idea why this functionality isn't exposed via a menu item. I just tried it with this tab and not only did I get full back history but it also had my partially entered comment in this form. Edit: holding ctrl while using back and refresh also duplicate a tab with predictable behaviour.
