Coupon fetching wrong view id on checkout pane ajax update

Hi everyone,

I'm getting a bug when i add a new coupon in the checkout step.

When i load the page, the correct view is loaded and as the "Actions" field to remove the coupon.

If i add a coupon and get the ajax refresh, the view loaded don't have the "Actions" field.

I noticed when editing 'Coupons' checkout pane

If i set Coupons Review Pane View to Checkout view, the ajax will load the the correct Checkout view and not the Review view

I would like to make a patch or help working on it but i have no idea where to start looking at.
