0. Open a document with links already in it.
- Click on a MediaWiki link, then click the icon to open the inspector.
- Click anywhere else in the document to lose focus.
- You're link has now been removed :(
Note that this doesn't happen if you have just created a link, or if you have edited a link, so I assume this is functionality for letting people abandon the creation of a link.
The only way to remove a link should be with the delete icon in the inspector, or clear formatting.
This doesn't appear to affect external links.
