In my tests, jsdom was throwing a "SecurityError" at HistoryImpl._sharedPushAndReplaceState (node_modules/react-scripts/node_modules/jsdom/lib/jsdom/living/window/History-impl.js:87:15)

This happens because document.URL defaults to "about:blank". Unfortunately, if you interact with the History object it tries and fails to parse the URL, causing a "SecurityError" to be thrown. Setting the default URL to "http://localhost" fixes this issue.
