When attempting to get the redirects to a page using `page.backlinks(filterRedirects=True)`, `IsNotRedirectPage` is raised. The page the exception claims is not a redirect, however, is a redirect.
`page.getReferences(redirectsOnly=True)` gives the same exception.
`page.getReferences(follow_redirects=False, redirectsOnly=True)` yields the same page twice.
