We want to share this function with HTMLMarqueeElement.js. I'll create
PrivateScriptUtilities.js so that you can add this kind of functions to the
common js file.

I've removed HTMLVideoElement.js. PrivateScriptUtilities.js is not needed so
far.

+        Object.defineProperty(prototype, propertyName, {
+            get: function() {
+                return this.getAttribute(attributeName) || '';
+            },
+            set: function(value) {
+                this.setAttribute(attributeName, value);
+            },
+            configurable: true,
+            enumerable: true,
+        });
+    }
+
+    reflectAttribute(HTMLVideoElementPrototype, 'width', 'width');
+    reflectAttribute(HTMLVideoElementPrototype, 'height', 'height');
+    //reflectAttribute(HTMLVideoElementPrototype, 'poster', 'poster');
+});
