+// 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.
