JQuery Mobile 1.4 - SilentScroll not working at all on IOS standalone web app

If you create a sample page similar to the silent scroll demo, but add the meta tag for web app capable.

Then load it up in safari and do a "Add to Homepage", launch it from the homepage so that it launches as a standalone sandboxed web app.  You can see that both of these buttons stop working.

Basically, calling slientscroll does nothing when in standalone mode.  This is annoying because there is no decent way to go back to your position in a listview when you return to a page, even if you store the value and try to silent scroll back.  You can use jquery's scrolltop function, but that causes a hideous FOUC effect.
