Description Daniel Ruspini 2008-06-09 16:58:23 PDT 
Using Fiddler I've found that when a CSS background-image property is overriden with another selector, the previously declared selector still initiates a request.

This does not happen in FF or IE, and became apparent when using a third-party JS library that included CSS and background images we did not want to use and thus targeted for overriding.  The 404's kept coming in though for Safari.

Example:
<html>
<body>

<style>
	.something {
		background: red url("images/foo.gif");
		width: 50px;
		height: 50px;
	}
	
	.something {
		background-image: none;
	}
</style>

<div class="something">
</div>
</body>
</html>


Fiddler says:
404 HTTP .... images/foo.gif

Yes, this is a known annoyance that i intend to fix (hopefully soon).  It applies to all image properties and not just to background-image.

I would say this bug is a bit more severe than "Normal". Any sort of plan for when a fix for this might come in?

Does this still occur with WebKit nightlies?

Fixed via bug 24223.
