gemini --version: 7.1.2 ... Hello. I try to hide scrollbar.

Test source code:

/* global gemini */
const urlList = require('./url-list');

urlList.forEach((url) => {
    gemini.suite(url + '-burger', (suite) => {
        suite
            .setUrl(url + '.html#mobile-menu')
            .before((actions) =>{
                actions.executeJS(() => {
                    const style = document.createElement('style');
                    const head = document.querySelector('head');
                    const scrollBarStyle = document.createTextNode('::-webkit-scrollbar {display: none;}');
                    head.appendChild(style);
                    style.appendChild(scrollBarStyle);
                });
            })
            .setCaptureElements('html')
            .capture('plain');
    });
});

I ger error:

[execute("(() => {\n\t\t\t\t\tlet style = document.createElement('style');\n\t\t\t\t\tlet head = document.querySelector('head');\n\t\t\t\t\tlet scrollBarStyle = document.createTextNode('::-webkit-scrollbar {display: none;}');\n\t\t\t\t\thead.appendChild(style);\n\t\t\t\t\tstyle.appendChild(scrollBarStyle);\n\t\t\t\t}(window));")] Error response status: 13, , UnknownError - An unknown server-side error occurred while processing the command. Selenium error: unknown error: Runtime.evaluate threw exception: SyntaxError: Unexpected token (

But this code works properly:

/* global gemini */
const urlList = require('./url-list');

urlList.forEach((url) => {
    gemini.suite(url + '-burger', (suite) => {
        suite
            .setUrl(url + '.html#mobile-menu')
            .before((actions) =>{
                actions.executeJS(function() {
                    let style = document.createElement('style');
                    let head = document.querySelector('head');
                    let scrollBarStyle = document.createTextNode('::-webkit-scrollbar {display: none;}');
                    head.appendChild(style);
                    style.appendChild(scrollBarStyle);
                });
            })
            .setCaptureElements('html')
            .capture('plain');
    });
});

What am I doing wrong?
