When Loading a page which has img elements with empty src attributes (for whatever reason), and HTTP requets using the URL of the containg document is called once more for each.

This could be harmful in the case of a page with sumbission information (sent more than once).

Reproducible: Always

Steps to Reproduce:
1. Install Live HTTP Headers
2. Go to http://www.habegger.fr/firefox.html 
3. Chekc that 4 HTTP request for the page have been sent
Actual Results:  
4 HTTP request

Expected Results:  
Only one HTTP request for the page should be sent

An empty src attribute in an iframe does not produce the same result.

Despite being in the wrong Product/Component (it's really an invalid HTML Parser or DOM non-bug), my favorite for duping these has always been bug 225554, for the explanations in it.

(Not only would <iframe src=""> not offer any options for content-negotiation, since you'd be asking for the same HTML you found it in, it would be a rather too-obvious source of infinite recursion.)
