iPhone-specific code is causing pages in all browsers to scroll to top

When trying to create a link to an anchor on a page I noticed some very strange behavior. The page would initially be positioned at the anchor, but would immediately scroll back to the top of the page. After some digging I found that this seems to be related to iPhone support.

In the page content there is this script:

<!-- start iPhone javascripts --><script type="text/javascript">
addLoadEvent(function()

{ setTimeout(hideAddressBar, 0); }

);</script>
<!-- end iPhone javascripts -->

And addLoadEvent is defined in .../s/1810/1/_/download/resources/com.atlassian.confluence.plugins.iphone/iphone.js:

—

/* Hides the scroll bar */
function hideAddressBar()

{ window.scrollTo(0, 1); }

/* Runs some onload initialize logic. There isn't anything here at the moment, but this is where
logic to tidy up the dashboard might go*/
function initializeIphone() {

}

/* Adds onload functions */
function addLoadEvent(func) {
var oldonload = window.onload;
if (typeof window.onload != 'function')

{ window.onload = func; }

else {
window.onload = function() {
if (oldonload)

{ oldonload(); }

func();
}
}
}

This code seem to be present and execute on a number of browsers that I've tested: Firefox 3.6, Safari 5.0 and Chrome 6.0 (all Mac OS X 10.6)
