Some WPT tests use <link rel="mismatch" href=...> to specify a reference that shouldn't match. On WPT this can be used along with other <link rel="match" ...> references or it can be used alone. See for example the test: https://github.com/web-platform-tests/wpt/blob/master/css/css-fonts/standard-font-family-20.html This test was imported on r255351 but the WebKit W3C test importer imported the mismatch as the reference causing the test to fail (see bug 206881) Other tests are likely affected by this, the one above its just an example.
