Chuck's excellent script to deal with tracker images without alt tag - the ones that mess up a11y scans!

document.addEventListener('DOMContentLoaded', function () {
    const targetNode = document.body;
    const callback = function (mutationsList) {
        for (let mutation of mutationsList) {
            if (mutation.type == 'childList') {
                mutation.addedNodes.forEach((node) => {
                    if (node && node.src && node.src.match(/.*pages02.net.*/).length >
                        0) {
                        observer.disconnect();
                        node.setAttribute("aria-hidden", true);
                        node.setAttribute("alt", "");
                    }
                });
            }
        }
    };
    const observer = new MutationObserver(callback);
    observer.observe(targetNode, {
        childList: true
    });
});
