I could not reproduce this using today's nightly build on a Nexus One.

What website are you performing a zoom on, Matt? I've been using reddit predominantly.

I've tried a few sites now, including Reddit.  I think I can reproduce this now.

It looks like the view of the page during the zoom animation is at a different zoom level than before or after the animation.  On http://limpet.net/mbrubeck/ the page appears smaller during animated zoom; http://reddit.com/ appears larger during animated zoom.  (Both in portrait mode - this seems to differ in landscape.)

This happens during multitouch zooming, and also during volume button (Maemo) or scroll wheel (desktop) zoom.

For example, if I load http://reddit.com in portrait mode the page is zoomed all the way out.  When I touch two fingers to the screen, it is suddenly zoomed in.  When I lift both fingers, the screen jumps back to the original zoom level.
