In attache You can found test html-file.

If we create image which points to absent image (we want to see at
"alt" text) from general html-tag, we can see Alt-text for each image.
But If these images is created by DOM, them ALT text will be showed
incorrectly.

This bug can be fully reproduced if test file will be placed on http.

Use Shift-Reload and Reload browser's button for reproduce bug: After
Shift-Reload browser showes correctly page, after 'Reload' browser
showes broken page.

If we open test-file from locally filesystem, browser will always show
broken page.



Reproducible: Always

Steps to Reproduce:
I tried firefox/windows, iceweasel/Debian, firefox/ubuntu. All of them have the bug.

I can reproduce the problem with different rendering for Shift-Reload / Reload
over HTTP in Firefox 3.5.3 on Linux.
It works for me in a trunk (3.7a1pre) build though:
http://ftp.mozilla.org/pub/mozilla.org/firefox/nightly/latest-mozilla-central/

The error is always present when loading file://
In both builds, hmm.
