        Add test "invalid-domain-change-throws-exception.html" to ensure a SECURITY_ERR exception is raised if an attempt is made to change document.domain to an invalid value. In the existing test case "basic-textareas.html", fix the faulty behavior of setting document.domain to invalid value, and replace the data URL to a file URL that points to "basic-textareas-standards.html" in order to make "basic-textareas.html" runnable in a browser.
