The following tests fail under --site-isolation because WKTR does not clear CORS preflight cache between tests: http/tests/xmlhttprequest/access-control-basic-allow-preflight-cache-invalidation-by-header.html http/tests/xmlhttprequest/access-control-basic-allow-preflight-cache-invalidation-by-method.html http/tests/xmlhttprequest/access-control-basic-allow-preflight-cache.html
