Wizard in a Navigator7 Page

I’m trying to use the Wizard combined with Navigator7 Pages. When I navigate to the page that contains the Wizard’s “intro” step, I can see the Wizard paint (it flashes on screen) but then it instantly gets over-painted with the content from the previous page. If I then immediately navigate to the same page where the wizard lives, things work normally. If I again immediately navigate to the same page where the wizard lives, it paints incorrectly again. I have a hunch that there is something wrong with URI handling, and I am looking for advice on how to debug this. Or, is the wizard known not to not support being hosted in a Navigator7 Page? Thanks.
