It only happens like that, last I checked, when an image is in them. I could make all the other items the same height too, but then the page would always be extended long like that. I know nothing about web coding and whatnot, but there would probably be a way to take the height of the image and approximate it to an equivalent new line length. Just don't know how and images aren't going to be there that often, so I don't think that it is needed that much.
