Iframe in phonegap doesn't scroll to the bottom of the page

I have a phonegap app that puts an iframe on the page. That works fine,
except that you can't scroll ("swipe") all the way to the bottom of that
iframe. It appears as though the bottom of the page is above where the
actual bottom is. And the fake bottom of the page is at different places
each time.
However, when you change the orientation of your phone, it now recognizes
the actual length of the page and now you can scroll all the way to the
bottom. It's like changing the orientation shocks it into behaving
properly.
I don't have this problem when just using a regular browser, only in
phonegap.
I'm wondering if maybe the outer page thinks the iframe page is a certain
length, then suddenly the iframe page grows bigger because an image was
finally loaded or something, and the outer page doesn't get properly
notified.
Any ideas? Any work-arounds?
