If we don't do this, when doing: self.config_stub.val.content.user_stylesheets = css_path then _update_stylesheet gets called before the stylesheet QWebEngineScript did run (as there was no load yet), so we get: [:2] Uncaught TypeError: Cannot read property 'stylesheet' of undefined! Instead, load the page first and then update the stylesheet. This tests that live updating works properly, and also makes sure we don't run into the problem described above.
