297370 - Browser can't change CSS-Style attributes of Document in newly opened Window

Status: RESOLVED INVALID

(Core :: DOM: Core & HTML, defect)

Description

[tux]

User-Agent:       Mozilla/5.0 (X11; U; Linux i686; de-DE; rv:1.7.8) Gecko/20050513 Firefox/1.0.4 (Debian package 1.0.4-1)
Build Identifier: Mozilla Firefox Version 1.0.4

If I open a new Window with JavaScript like in:
  var wdw = window.open(document.location);
then I can't modify the CSS-Attributes of the <div> Tags in the Document like in:
  wdw.document.getElementById("IdOfDivTag").style.width="100px";

Strangely it works if I open another Window with:
  var bla = window.open();
  bla.close();
or with:
  alert("BLA");
before trying to change the Attributes of the <div> Tags.
When the new (3rd) Window closes the Changes appear as wished in the 2nd one.

This happens on Mozilla (newest build), Firefox 1.0.4, Netscape 8 and Opera.
Therefore it works in the Microsoft Internet Explorer. Since this behaviour does
not seem logical to me I guess it's a bug.

Reproducible: Always

Steps to Reproduce:
1. create new window: var wdw = window.open(document.location);
2. change some attributes with getElementById():
wdw.document.getElementById("IdOfDivTag").style.width="100px";

Actual Results:  
nothing, the page in the new window looks exactly the same as in the 1st one

Expected Results:  
Changed the <div> Tags Attributes.

window opening is asynchronous...

Exactly.

That's because the window is created before the url of document gets actually
loaded in the window. The fetching and loading of the URL only starts after the
current script block finishes executing.

Resolving as INVALID since the current behavior is correct.
