@compojoom could you have a look at #93? is a hotfix, but if we remove it it fails. Ideally we should find somehow a exectueJS function to know when the Languages Chosen Selector is ready.
Because the problem is that if we don't wait by the time Selenium selects Danish as language...

... the javascript that refreshes the page with the loaded language is not ready. Therefore it never passes this line: https://github.com/joomla-projects/joomla-browser/blob/develop/src/JoomlaBrowser.php#L137
Do you think on a way we can get when this JS is loaded?
