This tests calling setData to set a URL in a null origin document. The URL should be sanitized when reading in another document.
To manually test, drag and drop the "1. Drag this" above to "2. Drop here" and "3. Drop here".

On success, you will see a series of "PASS" messages, followed by "TEST COMPLETE".
