VerifyBuyerError not caught or handled in validation

[joedarsh]

Describe the bug

If a customer manually declines/cancels SCA verification in banking app, the Square SDK verifyBuyer method throws a VerifyBuyerError, however there is no catch statement on these promises (assets/js/frontend/wc-square.js lines 309 and 414) which results in this error not being caught, the checkout form remaining locked, and no error message being displayed to the customer.

To reproduce

1. Enter credit card details and submit payment
2. When SCA challenge is presented, cancel it via bank
3. VerifyBuyerError is thrown uncaught and validation bails out with no error handling

Expected behavior

VerifyBuyerError is caught and passed to handle_error method to display message to user and unblock checkout UI.

Environment (please complete the following information):

• WordPress Version: 6.4.3
• WooCommerce Version: 8.7.0
• WooCommerce Square Plugin Version: 4.5.1
• Browser [e.g. chrome, safari] and Version: Chrome 122.0.6261.129

Additional details

I've tested locally adding a simple catch statement manually, and it resolved the issue:

this.get_verification_details().then((verificationDetails) => {
	return this.payments
	        .verifyBuyer(token, verificationDetails)
		.then((verificationResult) => {
			this.handle_verify_buyer_response(
				false,
				verificationResult
			);
		}) // no catch statement here so VerifyBuyerError is not caught

               // tested adding this manually resolves the issue:
               .catch((error) => {
                       this.handle_error([error]);
               });
});
