Previously we were computing the bottom edge of a line box by finding the bottommost fragment on the line. That method didn't give correct results for line boxes with no fragments (which is exactly what you get when inserting a bunch of <br> elements.) To cover all situations, we now keep track of the bottommost edge in the LineBox object itself.
