Although this is very easily arguable as a Won't Fix / not a bug, as how renaming it the same name may not make sense, this error is incorrect as we technically never attempt to add a second navigation menu, we just try to update it to the exact same name. FragmentEntry and AssetListEntry resolve this interaction differently, and because this one is different, I am filing it as a small bug.
Steps to Reproduce
- Rename a site navigation menu to the same name
It is allowed, even though if it doesn't make sense (don't show the user an error if not needed)
Duplicate Site Navigation Menu exception
Tested on Tomcat 9.0.17 + MySQL 5.7
