the iframe content will not be displayed correctly instead of a blank page if I placed it in a DIV and hide the DIV first.
Reproducible: Always
Steps to Reproduce:
created such a html page:
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml" lang="en">
<body>
<div id="testdiv"></div>
<p><input type=button onclick="document.getElementById('testdiv').style.display='none';" value="hide"> <input type=button onclick="document.getElementById('testdiv').style.display='';" value="show"></p>
<script>
document.getElementById('testdiv').innerHTML = 'Other information<br /><iframe frameborder=1 onload="javascript:{alert(\'call after iframe loaded.\');document.getElementById(\'testdiv\').style.display=\'\';}" src="http://www.google.com/" height=300 width=800></iframe>';
document.getElementById('testdiv').style.display='none';
</script>
</body>
</html>
Actual Results:
just create such a simple html page, and view it in firefox.
then u'll get a blank iframe content.
then after u click the 'hide' button and 'show' it, it'll displays OK!
but if I move the line
document.getElementById('testdiv').style.display='none';
above the line
document.getElementById('testdiv').innerHTML = ...
it seems everything is OK

Iframe is added to the "testDiv" with innerHTML. Testdiv:s display attribute is set to "none" right away, but changed to "block" once the iframe is loaded (onload on the iframe)

If you open the testcase locally, you will see a blinking cursor on the left part of the tab, where the favicon is

This loooks a bit like bug 308182
An additional problem I found is, after an Iframe has been scrolled and then is hided and displayed again, the scroll position is lost. This is particularly annoying in today's webapps, where iframes are becoming very popular to make fancy websites. The original testcase can also reproduce this behavior, just load the iframe, scroll it down, hide it, and then show it again. The scroll position is lost.
