Describe the bug
When I add a js code which prevents form from submitting, executes a function and after that submits. The website returns (client side) (Hidden field captcha) This field is required.. Script part of that I use (the one that messes up the captcha) is written below

    document.getElementById("referat").addEventListener("submit", async function(e) {
            e.preventDefault();
            var hiddenInput = document.createElement("input");
            hiddenInput.type = "hidden";
            hiddenInput.name = "late_fingerprint";
            hiddenInput.id = "late_fingerprint";
            document.getElementById("referat").appendChild(hiddenInput);
            await generateFingerprint("late_fingerprint");
            console.log("Late Fingerprint Value: ", document.getElementById("late_fingerprint").value);
            this.submit();
        });

To Reproduce
Steps to reproduce the behavior:
