+Subject: lib: use non-symbols in isURLInstance check
+
+This slightly changes the conditional used to determine whether or
+not something is a URL instance. Since Node.js adds symbols to the URL
+not specified by the WHATWG, those symbols are not present in other
+implementations (like Blink's) and therefore can cause false negatives.
+
+This fixes that by slightly changing the check to properties present
+in all URL instances as specified in the WHATWG spec.
+
