The above nav is the same component used in DEMO #1.
Below, I also have another element using Login-CV which is outside of any component. The element works fine, 100% as expected, and for some reason, the presence of that element on this page also makes the Login-CV in the top nav work properly as well.
If you take the component, and Unlink Instance, and check the Login-CV config for those elements, it looks weird. It's in some intermediate state where the config is blank-but-existing.
