android forms html iframe

Android tablet – Tabbing through input fields not does not work in forms within iframe

I built an HTML page with a form on it, and I’m embedding that page in an iframe. When navigating to the form page (without viewing through the iframe) on a Motorola Xoom, tabbing though the input fields works as it should. When viewing the page with the iframe on it, tabbing through the form does not work any more. Any thoughts? Insights?
