UNIONPAY, WECHAT, ALIPAY After click "Back To Merchant" without complete payment land in thankyou page

[GabrieleRizzo19]

In live mode, if the payment isn't completed and click on "Back To merchant" redirect lands you to thankyou page instead of payment page.
I can't test it in sandbox mode because there is not "Back to merchant" button. Click "refused" or "error" redirect you to payment page with error as expected.

To Reproduce

1. Use production mode, NOT test/sandbox mode
2. Make checkout and select UnionPay, WeChat or Alipay for pay
3. On payment provider page click "Back To Merchant" button without complete payment

Expected behavior
Redirect lands you to payment page highliting failed payment.

Magento version
2.4.4-p6

Plugin version
