These should probably only respond to click events although it seems they currently support the click and drag functionality of a drop down box. If you are editing a textarea in the right hand panel and you click and drag from right to left to select all the text you will often end up with your mouse over the outline widget. Releasing your mouse here will cause you to jump to a random page.
