Style removal on using accordionVertical animation

[MRezaSafari]

The style attribute should be removed after the animation end when using the accordionVertical animation.
although the style remain with the property transform-origin with the value of "center top 0px"

It's not gonna make any problem but I think it must be more clear if you remove the style attribute at all.

Thank you.

Yeah, good catch. We ought to clean up after ourselves better!
