When encountering a file in the lightbox whose contents cannot be found, the lightbox header height shrinks to the height of it's contents, which is smaller than a lightbox header with all the appropriate elements. I wonder if we should add a min- or fixed height to provide a more consistent experience? Attaching a screenshot here:
