This is not exactly a problem with Yahoo!, but rather a problem with the way browsers tend to render HTML when forced to deal with broken tags.
So it's a problem with Yahoo, as they allow the email, to write to places on the screen that is not part of the email. I agree this is certainly down to the liberalness of the browsers parser, but that doesn't mean yahoo can ignore it, it's just a demonstration of how difficult a job it is for people who want to accept arbitrary HTML to be secure for their user Of course there is a pretty simple solution, which is to just use an IFRAME, then there's no way the email to escape into the surrounding chrome.
