> Consider the following scenario:
> - I have a BasePage that I add a feedback panel to.  I want it to only render feedback messages that have not been rendered by any other feedback panels
> - I have a feedback border that implements IFeedback, and inside it, I also have a FeedbackPanel.  I want the feedback panel to only render the messages pertaining to the components within the border.
> To accomplish this, I put the creation of the feedback panel in the BasePage in onBeforeRender so that my component hierarchy (including the border and it's child feedback panel) is created before I add myself to the hierarchy.  By doing this, I expect my page to be the last IFeedback to appear in the feedback list.
> But alas, when Component#beforeRender creates the list of IFeedback components, it effectively stops the traversal of any IFeedback#beforeRender calls because it does not call internalBeforeRender().
> The attached quickstart demonstrates the problem, and the patch fixes it.
