In Firefox, an iframe cannot be really destroyed if you use delete keyword. (My version is Firefox 3.63 under Windows XP, 2011/11/14.) This is not required in all other major browsers.

Reproducible: Always

Steps to Reproduce:
   1. Use Firefox to browse this page.
   2. Press "Create Iframe"" button.
   3. Press "Insert HTML" button.
   4. Press "Destroy Iframe" button.
   5. Press "Create Iframe" button (Again).
   6. Press "Insert HTML" again, your browser reports an error. This won't happen in other major browsers including IE.

Actual Results:  
docEl is null

Expected Results:  
Show inject iframe successfully without error.

If I change window.frames["foo"] to window.frames[0] then it works.
But window.frames[0].name is "foo".  Odd...

Dupe of bug 498904?
