Error Subflow doesn't catch any errors of Authorize Tokenized Payment action in Checkout flow

If Authorize Tokenized Payment action of the Checkout_Main_Checkout.flow throws an exception and returns an error, the flow doesn't stop and finishes as if the job was successfully completed.

Start with the Checkout_Main_Checkout.flow and trace the Authorize Tokenized Payment action's exception and error path. Reproduce the failing checkout behavior, then verify that an error stops the flow instead of allowing a successful completion.
