Description

If you add a Link Block to the navigation block, add a link, and then try to edit the label/text the "Add link" prompt shows up despite a link already being added. This makes it seem as though by deleting the label, you have also removed the link. cc @jasmussen since you're working on this!

Step-by-step reproduction instructions

1. Add a navigation block
2. Add a link block
3. Add a link
4. Edit the text of the link you added and fully remove the text.
5. See "Add link" but confirm the link is already still added.

Expected behaviour

I expect the "Add link" prompt to say "Add text" or "Add label" since a link is already in place.

Actual behaviour

The "Add link" prompt shows up.
