[Feature request] set-cookie scriptlet

[scripthunter7]

As far as I can see, there is a cookie-remover scriptlet, but there is no way to override a cookie (but correct me if I'm wrong).

There are several pages that shows aggressive popups (which is block scrolling), and displaying of these popups usually depends on 1 cookie. For example, egeszsegkalauz.hu shows popup this way:

Show JS

$(window).ready(() => {
    if (!getCookie('isLeavingPopUpReady') && document.querySelector('.leavingPopupLayer')) {
        console.log("first");
        const showPopup = () => {
            setCookie('isLeavingPopUpReady', false, 3);
            document.querySelector('body').style.overflow = 'hidden';
            document.querySelector('.leavingPopupLayer').style.display = 'block';
            document.querySelector('.leavingPopupLayer div').classList.add('fade-in');
        };

        // ...
    }
});

It would be much easier to block these popups if cookie overwrite was available:

egeszsegkalauz.hu##+js(set-cookie, isLeavingPopUpReady, 1)

For security reasons, set-cookie should only take predefined values, just like set-constant.

AdGuard has a set-cookie scriptlet, reference: https://github.com/AdguardTeam/Scriptlets/blob/master/wiki/about-scriptlets.md#set-cookie

Hmm, right, sorry. Although it's been more than 1 year since then. As far as I know, this scriptlet works without problems in AdGuard.
