animate function not working properly in Chrome

[noel_fb@…]

Push this code into a BODY tag:

<div id="xxx" style="position: absolute;right: 40px;top: 0;background-color: #EEE;width: 400px;height: inherit;">PRUEBA</div>

And then try this: $('#xxx').animate({'left': '50%'}, 1000);

In FF is working properly... But NOT in Chrome. In Chrome the element start in the LEFT, and then move to the right (fail). In FF start in the original position, and then move to the left (ok).

Sorry for my bad english.

REMEMBER TRY IT IN GOOGLE CHROME!!!

The problem occurs when an element has defined a "right" in "px", and the animation is defined to make the "right" in "%"

I confirm this bug, it should not be closed.

It doesn't make sense to animate the left property as a percentage. A percentage of WHAT?

[Broda Noel]

A percentage of the parent! or representative!. So we can say: "align left 50 pixels of WHAT?"

[Broda Noel]

And, YES, is a bug.

Definitely a bug and should be reopened:

Another fiddle (try that in Chrome): ​http://jsfiddle.net/lucasprus/GjezT/1/

Inspect the green box and see how 'left' property changes if you click 'Animate left' or 'Animate right'.

That works fine in the rest of my browsers.
