You can select any spans and drag them. It works fine untill the nested span is also selected. The nested span will not drag right jumping from place to place due to its relative position

• Select with the mouse span1 and span2. Drag them arround, it works right
• Select with the mouse span1, span2 and nested span4. Drag them arround, the positions get messed up
