When sorting a metabox, a clone of that metabox is created as a drag/drop "helper". Previously, any checked radio input in the original metabox would become unchecked, when its clone "helper" was inserted into the DOM (since only one radio within a set of radios of the same name can be checked). Continued use of the clone helper is important so that the element being dragged isn't subject to the click and other event handlers attached to the real metabox, so we can't just switch to dragging around the real metabox. See, for example, comment:10:ticket:16972. Preserve the radios' state via some name attribute trickery.
