Description
If you try to animate a background-image by background-position and the initial-Y-position of the background is negative, then the animate-command will start at zero instead at the y position.
image.css({'background-position': '200px -200px'});
image.animate({'background-position': '0px 0px'}, 5000);
As you can see in this example the background will be first set to 200px -200px and then when the animation begins it jumps to 200px 0px and animates to 0px 0px.

If the main jQuery animate() function cannot support all standard cross-browser CSS properties, and we have to install hooks piecemeal to support those other properties, why have animate() be a part of core jQuery at all?
I move for jQuery animate() to support multiple value CSS properties by default or for animate() to be extracted from jQuery core.

#11270 is a duplicate of this ticket.
You might want to checkout the jQuery-cssHooks plugin (bgpos.js) which uses the new cssHooks functionality to animate background-position correctly. The documentation of
css()andanimate()clearly state that at the moment only properties which areare supported.
If the plugin works out for you might also try to do this yourself using the animate() step callback. Please report back if this suggestion work out for you.
