The customer reported an issue with adding links to a text in the Rich Text Editor. The link is added even though no content was selected via UDW.

Steps to reproduce:

1. Login to the admin panel.
2. Create content with RichText field type (ezrichtext).
3. Add some text inside RichText field.
4. Select some text and click on "link" button
5. Enter UDW to select some content
6. Don't select any content object but hit "Cancel"

Result:
The link pointing to the current content object is added anyway.
