Adds a routed event handler for a specified routed event, adding the handler to the handler collection on the current element. Specify handledEventsToo as true to have the provided handler be invoked for routed event that had already been marked as handled by another element along the event route.

Implements ArrangeCore(Rect) (defined as virtual in UIElement) and seals the implementation.

Called to arrange and size the content of a Control object.

Starts an animation for a specified animated property on this element.

Create the underlying CefBrowser instance with the specified initialSize. This method should only be used in instances where you need the browser to load before it's attached to the Visual Tree.

Create the underlying Browser instance, can be overriden to defer control creation The browser will only be created when size > Size(0,0). If you specify a positive size then the browser will be created, if the ActualWidth and ActualHeight properties are in reality still 0 then you'll likely end up with a browser that won't render.
