We should start seeking from the child-at-start/end-offset, rather than the selection container. The logic to select the starting node was backwards too... If we're finding backwards we want to start looking from the beginning of the range and vice versa. But I think that doesn't really matter since nsWebBrowserFind always gives us a start range with start == end.
