You can stop checkout success page redirection after refresh page, for styling and testing purposes, with this below code:

Go to this file:

vendor/magento/module-checkout/Controller/Onepage/Success.php   

and comment Out Line No : 22

//$session->clearQuote();   

Now you will be able to refresh and debug success page without redirecting.
