If the document never opts in, it'll never get rendered, but is still loaded.

The simplest way to emulate it would be to make the <iframe> act as if it was display:none. / Jonas </pre> </div> <div class="msgButtons margintopdouble"> <ul class="overflow"> <li class="msgButtonItems"><a class="button buttonleft " accesskey="p" href="msg33140.html">Previous message</a></li> <li class="msgButtonItems textaligncenter"><a class="button" accesskey="c" href="thrd10.html#33228">View by thread</a></li> <li class="msgButtonItems textaligncenter"><a class="button" accesskey="i" href="maillist.html#33228">View by date</a></li> <li class="msgButtonItems textalignright"><a class="button buttonright " accesskey="n" href="msg31158.html">Next message</a></li> </ul> </div> <a name="tslice"></a> <div class="tSliceList margintopdouble"> <ul class="icons monospace"> <li class="icons-email"><span class="subject"><a href="msg31161.html">Re: [whatwg] AllowSeamless</a></span> <span class="sender italic">Markus Ernst</span></li> <li><ul> <li class="icons-email"><span class="subject"><a href="msg31162.html">Re: [whatwg] AllowSeamless</a></span> <span class="sender italic">Markus Ernst</span></li> <li class="icons-email"><span class="subject"><a href="msg31163.html">Re: [whatwg] AllowSeamless</a></span> <span class="sender italic">Adam Barth</span></li> <li><ul> <li class="icons-email"><span class="subject"><a href="msg31164.html">Re: [whatwg] AllowSeamless</a></span> <span class="sender italic">Markus Ernst</span></li> <li><ul> <li class="icons-email"><span class="subject"><a href="msg33087.html">[whatwg] Making cross-origin <iframe sea...</a></span> <span class="sender italic">Ian Hickson</span></li> <li><ul> <li class="icons-email"><span class="subject"><a href="msg33090.html">Re: [whatwg] Making cross-origin <if...</a></span> <span class="sender italic">Mikko Rantalainen</span></li> <li class="icons-email"><span class="subject"><a href="msg33093.html">Re: [whatwg] Making cross-origin <if...</a></span> <span class="sender italic">Adam Barth</span></li> <li><ul> <li class="icons-email"><span class="subject"><a href="msg33131.html">Re: [whatwg] Making cross-origin &...</a></span> <span class="sender italic">Jonas Sicking</span></li> <li><ul> <li class="icons-email"><span class="subject"><a href="msg33137.html">Re: [whatwg] Making cross-orig...</a></span> <span class="sender italic">Markus Ernst</span></li> <li class="icons-email"><span class="subject"><a href="msg33140.html">Re: [whatwg] Making cross-orig...</a></span> <span class="sender italic">Ian Hickson</span></li> <li class="icons-email tSliceCur"><span class="subject">Re: [whatwg] Making cross-orig...</span> <span class="sender italic">Jonas Sicking</span></li> </ul> </ul> </ul> </ul> </ul> </ul> </ul> </ul> </div> <div class="overflow msgActions margintopdouble"> <div class="msgReply" > <h2> Reply via email to </h2> <form method="POST" action="/mailto.php"> <input type="hidden" name="subject" value="Re: [whatwg] Making cross-origin <iframe seamless=""> (partly) usable"> <input type="hidden" name="msgid" value="CA+c2ei9PQF==ufmj_2i+vMAtLje1ONfi1Tid4+ReisW53kQwyg@mail.gmail.com"> <input type="hidden" name="relpath" value="whatwg@lists.whatwg.org/msg33228.html"> <input type="submit" value=" Jonas Sicking "> </form> </div> </div> </div> <div class="aside" role="complementary"> <div class="logo"> <a href="/"><img src="/logo.png" width=247 height=88 alt="The Mail Archive"></a> </div> <form class="overflow" action="/search" method="get"> <input type="hidden" name="l" value="whatwg@lists.whatwg.org"> <label class="hidden" for="q">Search the site</label> <input class="submittext" type="text" id="q" name="q" placeholder="Search whatwg"> <input class="submitbutton" name="submit" type="image" src="/submit.png" alt="Submit"> </form> <div class="nav margintop" id="nav" role="navigation"> <ul class="icons font16"> <li class="icons-home"><a href="/">The Mail Archive home</a></li> <li class="icons-list"><a href="/whatwg@lists.whatwg.org/">whatwg -
