   4 <div>This tests that a drop handler's default action must be prevented in order to stop navigation.
   5 Otherwise, if event.preventDefault() is not called, navigation should occur. To test manually,
   6 simply drag and drop another link or HTML file on this page. If navigation occurs, then the test
   7 passed.</div>
