CSS3 background image transition

Question

I'm trying to make a "fade-in fade-out" effect using the CSS transition. But I can't get this to work with the background image...

The CSS:

.title a {
    display: block;
    width: 340px;
    height: 338px;
    color: black;
    background: transparent;
    /* TRANSITION */
    -webkit-transition: background 1s;
    -moz-transition: background 1s;
    -o-transition: background 1s;
    transition: background 1s;
}

.title a:hover {
    background: transparent;
    background: url(https://lh3.googleusercontent.com/-p1nr1fkWKUo/T0zUp5CLO3I/AAAAAAAAAWg/jDiQ0cUBuKA/s800/red-pattern.png) repeat;
    /* TRANSITION */
    -webkit-transition: background 1s;
    -moz-transition: background 1s;
    -o-transition: background 1s;
    transition: background 1s;
}​

You can transition background-image. Use the CSS below on the img element:

-webkit-transition: background-image 0.2s ease-in-out;
transition: background-image 0.2s ease-in-out;

This is supported natively by Chrome, Opera and Safari. Firefox hasn't implemented it yet (bugzil.la). Not sure about IE.
