Multi-Domains and Stripe Gateway conflict with Pro-sites

Multi-Domains is causing a conflict with Stripe payment gateway in Pro-Sites. When going to the Pro-Sites checkout page and choosing a site to upgrade if Multi-Domains is activated its stripping out the main-site domain which is what all the plans are based on. When deactivating Multi-Domains Stripe Gateway works fine.

I will grant access for anyone who wants to confirm this behavior.
