// The results of this test are all over the map due to browsers behaving very differently for
// javascript: URLs.
//
// Chromium is pretty close execution-wise, but it parses javascript: URLs incorrectly.
// Gecko navigates to non-string return values of the result of executing a javascript: URL.
// WebKit executes javascript: URLs too early and has a harness error due to URL parsing.
//
// The expectations below should match the HTML and URL standards.
