617369 - The state is kept for dynamically generated frames added during "load" or "DOMContentLoaded" events

Status: RESOLVED DUPLICATE of bug 462076

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

Description

[Julien Wajsberg [:julienw] (PTO -> Aug 14)]

User-Agent:       Mozilla/5.0 (X11; U; Linux i686; fr; rv:1.9.2.12) Gecko/20101026 Firefox/3.6.12
Build Identifier: Mozilla/5.0 (X11; U; Linux i686; fr; rv:1.9.2.12) Gecko/20101026 Firefox/3.6.12

In an appplication, we generate iframes dynamically when the DOMContentLoaded event fires. And we set the src attribute to a specific URL.

We found that when the user reloads the page, Firefox displays the page that was displayed before reload, instead of using the provided src.

I understand this is wanted behaviour for IFrames specified in the HTML file, but I feel this is wrong for dynamically generated IFrames.

I made a testcase which shows just that. It inserts 3 Iframes with random urls when the DOMContentLoaded event fires. There is also a "p" element with the same value as the "src", to be able to compare.

Reproducible: Always

Steps to Reproduce:
1. load attached testcase
2. reload attached testcase (with F5 or the reload button)
Actual Results:  
The IFrames contents are the same as before the reload.

Expected Results:  
The IFrames contents should be the website indicated by the url in the paragraph just ahead.

- shift + reload works fine
- Chromium 6 works fine
- Firefox 4b7 works fine

Simple workaround :
- specifying the src attribute after appendChild.

Attachment: same testcase, but with the workaround making it working

So FF4b7 works fine?
Then this sounds very much like a dup of bug 462076.
