Wrong 404 fallback in checkout page

[giotigre]

When the checkout form is submitted, no matter if you really submit the data to the server or stick to the demo submit, instead of correctly routing to the /checkout/success message page, the page redirects to the 404 page.

I've tried through cloning the shop through github, through the Polymer CLI, and then realized the error also shows on the live polymer shop.

Is this an actual 404 fallback error or am I missing something?

Grab from the live shop:

@giodicii Thanks for the report and this is a regression caused by the changes we did to add 404 support. I have reverted the changes that causing the incorrect behavior and we will push a build to the live demo app soon.

Should be all fixed now.
