Update Cart button problem...

Hi, I think I've found an issue with the Update Cart button as I see the same issue I'm having in my development as I see on the perch nest running demo site.

Without the coupon form appearing on the same page as the cart listing, I can change the cart quantities and update cart correctly tallies the new quantities and totals...

But I think when there's another form on the page, it gets confused... and update cart applies the old values to the cart...

I see that on /shop/cart of the demo site and locally... locally I am able to remove the promo form and cart update works...

Or maybe I'm missing something again, I don't know.
