if you edit the html widget from the homepage (so returnurl points to /) then no messages are being shown -- they are delayed until you navigate to some other (admin-)page; just refreshing the home page does not help.
The problem is most likely related to HomeController.cs which creates a new viewresult which is missing the TempData collection. I added this for testing purposes: The messages now appear as expected on the home page but every message is being shown twice.
