Attachment: testcase

Hi,
I've created an image with document.createElement("img");

then I've defined src and alt attributes.
src points to a non existent file.
When adding image to the document, alternate text is not displayed. It works correctly in ie7 and opera.
when modifying innerHTML of image parent element, alternate text is then displayed.

After opening the bug, I discovered the bug does not appear.
Actually, problem only happens with local file.
Saving the file to the disk, and opening it from there should trigger the bug.
So, this is less annoying (but still annoying for web development)

If you're doing web development against file://, you're doing it wrong, since so many things work different for file:// and http://.... especially in a world with CORS.

That said, we should consider fixing this independently of bug 282432, as we fixed bug 269125.  Ms2ger, are you interested?

If this is only a problem for file: URLs, not really.
