Describe the bug
It seems that in 9.2.0 the payment request buttons now for some reason don’t take up 100% width of their container, which prevents a styling mismatch between the normal add to cart button and the ECE buttons

It’s to do with the change in the file

/build/express_checkout.css

As now it’s including all this

#wc-stripe-express-checkout-element iframe {
max-width:unset
}

#wc-stripe-express-checkout-element {
margin-bottom:12px;
display:flex;
gap:10px;
flex-wrap:wrap;
justify-content:center
}

Whereas previously all that was there had nothing to do with the display flex or wrap

To Reproduce
Steps to reproduce the behavior:

1. Go to 'any product page where there is just GPay and Apple Pay or checkout'
2. Click on '....'
3. Scroll down to 'payment request button and see the smaller sizing now because of the styling'
4. See error

Expected behavior
Buttons to be full width as no AmazonPay is in the UK so all UK stores have this styling issuing due to the new wrap that's been added
