The javascript has a nondeterministic behavior in WebKit (Safari) but it's deterministic in FireFox 3 + IE7 - in this example you have a frame that accesses javascript properties from the 2nd frame.

I started spying in a local proxy and noticed that the 2nd frame is never getting called...Perhaps what should happen is all frames get downloaded first, and then only ever all frames are downloaded any onload() is triggered?

index.html:

Main Page
<meta http-equiv="content-type" content="text/html; charset=ISO-8859-1">
</head>
<script>

    document.write('<FRAMESET rows="*%,140">');
    document.write('<FRAME name=one frameborder=0 src=one.html>');      
    document.write('<FRAME name=two frameborder=0 src=two.html>');
    document.write('</FRAMSET>');
</script>

</html>

one.html:

if( window.parent.frames[1].document.frm.one == undefined) return;
window.parent.frames[1].document.frm.one.value = "";

}
</script>

The Scala Code:
val webClient = new WebClient(BrowserVersion.FIREFOX_3);
var page = webClient.getPageHtmlPage

HtmlFrame2Test.postponeLoading() was added as @NotYetImplemented

The attached patch fixes the case, but HtmlFrameTest.frameScriptReplaceOtherFrame() fails
