更新后 Gmail 的 Tampermonkey 脚本问题

Issues with Tampermonkey script for Gmail after update

我在 Chrome 中使用了一个 Tampermonkey 脚本,它增加了 Gmail 中 "Move to" 和 "Label as" 菜单的最大长度。当 Tampermonkey 几个月前自动更新到最新的主要版本时,脚本停止工作。几年前,我们的开发经理帮助我编写了脚本,但由于我是一名业余开发人员,所以我不太幸运地弄清楚为什么它不再起作用了。

(function($){
    jq = $;

    // fix css and ui
    fix.go = function(){

        // update the css/styles of things we dont like
        $('body').append(" <style id='monkey'> " +
                         " .J-M-Jz { max-height: none !important; }.J-M {max-height: 800px !important; } </style>" );

    };    

})(jQuery.noConflict());

document.addEventListener("DOMContentLoaded", function(event) {
    //console.log("DOM fully loaded and parsed");
    if(window.location == window.parent.location) {
        if (document.getElementById("loading")) {
            fix.go();

    }

;(function ($, window) {
    var intervals = {};
    var removeListener = function(selector) {
        if (intervals[selector]) {
            window.clearInterval(intervals[selector]);

    $.fn.waitUntilExists = function(handler, shouldRunHandlerOnce, isChild) {

        var selector = this.selector;
        var $this = $(selector);
        var $elements = $this.not(function() { return $(this).data(found); });

        if (handler === 'remove') {
            // Hijack and remove interval immediately if the code requests
            removeListener(selector);
        }
        else {
            // Run the handler on all found elements and mark as found
            $elements.each(handler).data(found, true);

            if (shouldRunHandlerOnce && $this.length) {
                // Element was found, implying the handler already ran for all 
                // matched elements
                removeListener(selector);
            }
            else if (!isChild) {
                // If this is a recurring search or if the target has not yet been 
                // found, create an interval to continue searching for the target
                intervals[selector] = window.setInterval(function () {
                    $this.waitUntilExists(handler, shouldRunHandlerOnce, true);
                }, 500);
            }
                }
        return $this;
    };

}(jQuery, window));

如果我检查 Chrome 中的元素以打开开发控制台,我可以看到 Tampermonkey 没有注入新值。如果我手动更改开发控制台中的值,我就能生成我正在寻找的结果。请参阅下面的 Imgur 相册中的屏幕截图(显然我不能 post 任何图像或包含两个以上的链接,因为我至少需要 10 个声望...)

如您所见,我可以通过控制台修改菜单的长度。 Tampermonkey 没有这样做,我猜这是因为我的脚本中的某些内容已经过时了。任何帮助将不胜感激。

我决定从头开始。我能够使用以下脚本完成同样的事情:
