Status: UNCONFIRMED

(Core :: DOM: Core & HTML, defect, P5)

Description

[Salar al Khafaji]

User-Agent:       Mozilla/5.0 (Macintosh; U; Intel Mac OS X 10_6; en-us) AppleWebKit/531.9 (KHTML, like Gecko) Version/4.0.3 Safari/531.9

Manipulating the .contentWindow or .contentDocument property of a newly created (and inserted) iframe doesn't work in Firefox. It only works after the function has returned, which is not the expected behavior.

Reproducible: Always

Steps to Reproduce:
1. Create an iframe using iframe = document.createElement("iframe");
2. Insert the iframe somewhere in to the document, e.g. using document.body.appendChild(iframe);
3. Try to use iframe.contentDocument or iframe.contentWindow.document to manipulate the iframe DOM.

(See URL for an example of this.)
Actual Results:  
Nothing happens. In the example URL, only "bar" is visible in the iframe.

Expected Results:  
DOM manipulation on iframes should be available immediately. In the example URL, the expected result is "Foobar".

All of this works perfectly in Safari 4.
