Despite obeying normative URL rules, I still think this is a bug. I can't think
of a reason why anyone would write <img src="">, <script src="">, or <link
href=""> except by accident (most likely, the failing of a dynamically-created
page). I'd submit that any empty string for an external resource is an invalid
URI and therefore should be ignored. There are enough alternatives that if the
author intends to load the current page, it can still easy be done, such as
<img src="/"> or <img src="#">.

<iframe src=""> ignores the empty source in WebKit currently, so it seems that
this behavior isn't evenly applied even within WebKit. Opera doesn't have this
problem with <img>, <script>, or <link>. Firefox behaves the same as WebKit. IE
only has this problem for <img> but not for <script> or <link>.

This issue causes a lot of problems for developers, so it would be good to
address it.
