Web page or screen you were on when you saw the issue: http://www.heise.de/newsticker/meldung/iPhone-4S-mit-Ortungsschwierigkeiten-1396347.html But happens on a lot of sites Steps to reproduce: 1. double tap to zoom in the paragraph of text What I get: If I can see the paragraph of text already, but the page is still loading, double tapping will zooms in first, than zooms out again, once the page is fully loaded. What you expected: just zoom in and stay zoomed in, even if the page finishes loading.
