Have a link [[Foo]] which is a redirect to [[Foobar]].
Inspect link; it will suggest:
New pages
Foo
Existing pages
Foobar
This is because "Foo" does not come back in the list of pages you can link to - which is filtered to remove redirects - but we should special-case the existing link.
Version: unspecified
