65718	Multisite: the blogname is required during site creation but can be emptied later	afercia		"Discovered after Copilot review on an unrelated PR, see https://github.com/WordPress/wordpress-develop/pull/12683#discussion_r3653345968

When creating a new site, the 'Site Title' field is required. The value entered there is then used for the site `blogname`.

However, after the site is created, it is possible to edit the site, manually empty the `blogname` field and save. 

At this point, the site will not have a `blogname` option, which is a problem because it is expected to be there and it is used in various parts of the admin including visually hidden text, aria-labels etc."	defect (bug)	new	normal	Future Release	Networks and Sites		normal		has-patch needs-testing		multisite
