Even when trimURLs is true, for some URLs we still display http://, for instance: http://localhost/+Blob/something/foo bar + baz/ If you load this (doesn't matter if it's a 404) and then select from after "foo" to the beginning, we duplicate the "http://" protocol specifier. Reproducible on 49 beta as well as nightly.
