Search on the modern google homepage does not work

Summary

When I go to the Google homepage and enter a query and hit enter, nothing happens.

The modern google homepage requires a fake useragent, such as Chrome on macOS

Operating system

Linux

Using ladybird https://github.com/LadybirdBrowser/ladybird/commit/3e57f472f58344d13347850f4debaf0e9194e6e2

Re-verified on https://github.com/LadybirdBrowser/ladybird/commit/1388b6866e25447335a7f5bd25d3153c710c0670

Steps to reproduce

Type any text in the textarea
Hit enter

Expected behavior

The website detects the query being submitted and redirects to the search results page

Actual behavior

No query is performed, sometimes a new line is created

URL for a reduced test case

https://www.google.com/

HTML/SVG/etc. source for a reduced test case

        </div>
        <script nonce="">(function () {
                var a = this || self; var c = document.querySelector("form"); if (c) { var d = function (b) { b.key !== "Enter" || b.shiftKey || (b.preventDefault(), c.submit && c.submit()) }; c.addEventListener("keydown", d); a.sbmlhf = d };
            }).call(this);</script>
    </form>
</body>
