Thank you page: Shopify.Checkout.page has unknown value "checkout_one_thank_you"

[sashWTF]

Hey there,

I'm currently trying to install Trusted Shops Toolkit in one of my customers' shops. It seems that the plugin ensures `Shopify.Checkout.page` is set to `thank_you`, as documented here: https://shopify.dev/themes/architecture/layouts/checkout-liquid#shopify-checkout-page

But for some reason, in my customer's shop, the property is set to `checkout_one_thank_you`:

That value is not documented anywhere, nor can I find anything on Google.

Why does this value appear?

Trusted Shops replied to my mail, telling me that shopify seems to be rolling out a single page checkout for some shops. Right now, the trusted shops app does not support these checkout pages, so we had to set up the trusted shops widget manually.
