Cross domain aliases can break aliases overview in admin dashboard

[y3n4]

Uncaught PHP Exception Twig\Error\RuntimeError: "An exception has been thrown during the rendering of a template ("Entity of type 'App\Entity\User' for IDs id(X) was not found")." at list_many_to_one.html.twig line 29"

Seems like if an alias from alias@example.net for user@example.org exists, this breaks the Aliases overview for the domain admin of example.net, because it will try to fetch the owner of the alias, but not find it due to doctrine filter.

Filtering cross domain requests is intended, but it should be handled gracefully.
