        }
        .error {

            margin-top: 5px;
        }
    </style>
</head>
<body>

    <h1>Formulaire de saisie IBAN</h1>

    <form id="ibanForm" action="#" method="post">
        <label for="iban">IBAN :</label>
        <input type="text" value="FR7630004000031234567890143" id="iban" name="iban" placeholder="FRXX XXXX XXXX XXXX XXXX XXXX XXX" required>
        <div id="ibanError" class="error"></div>

        <input type="submit" value="Envoyer">
    </form>

    <script>
        const form = document.getElementById('ibanForm');
        const ibanInput = document.getElementById('iban');
        const ibanError = document.getElementById('ibanError');

        form.addEventListener('submit', function(event) {
            ibanError.textContent = ''; // Efface les erreurs précédentes
            const ibanValue = ibanInput.value.trim().replace(/\s/g, ''); // Supprime les espaces

            if (!isValidIBAN(ibanValue)) {
                ibanError.textContent = 'Veuillez saisir un IBAN valide.';
                event.preventDefault(); // Empêche la soumission du formulaire
            }
        });

        function isValidIBAN(iban) {
        if (!iban) return false;

        iban = iban.toUpperCase().replace(/ /g, "");

        if (!/^[A-Z]{2}[0-9]{2}[A-Z0-9]{1,30}$/.test(iban)) return false;

        iban = iban.substring(4) + iban.substring(0, 4);
        let digits = "";
        for (let i in iban) {
            digits += parseInt(iban[i], 36);
        }
        return (parseInt(digits) % 97 === 1);

        }
    </script>

</body>
</html>

It crash.

But no crash without allow style

cefclient.exe --multi-threaded-message-loop --no-sandbox

The IBAN manager is display :

{DFC5A5DA-5508-42A3-BFEE-8644745A6F21}

I search a way to disable the IBAN manager without sucess.

Expected behavior

Not crash :)
