I've found what looks like a bug in this datatype, but wondering if anyone else has had/is having the same issue.

If you're on a node in the content tree which has a property of this type, but you have NO links added and you publish the page. Then, when you try to add links they are not added.

Publishing the page, clicking on another node and returning to this shows that there are no links, but at this point you are able to add them.

Hopefully this description makes sense.
