When trying to navigate the content with the UDW, if we have at least 51 content objects under the same location we will end up with a spinning wheel in the end of the list.

1. Create 51 content objects under the same location
2. Start creating a new article
3. Click the icon to add an embed object
4. Navigate to your location when you have the 51 content objects

You will get the spinning wheel, which will not go away even if there's nothing more to load.
