I think that's a different issue. The Chromium change was very intentional to work around an otherwise-unavoidable failure mode users would encounter (some pages don't restore correctly if you navigate off of them, and backspace also meaning "delete previous character" meant that having it overloaded as the "go back a page" operator too often led to undesired navigation events). Incidentally, aren't there already Chrome extensions to change the behavior to what it was originally?
