开启脚本会导致A、B站等出现暂停不了，视频缓冲出现问题，隐身模式只启用该脚本一样复现了问题。
还是限制一下作用域名比较好吧，这种全局作用很容易出现BUG

我贴下console信息给你，我的猜测原因是 const DOC = document;导致的问题，这个变量名字太常用了，A站也使用了同一个变量名，注释掉这行后正常了

感谢补充，基本是 addEventListener 事件的劫持代码导致

// 大约 52 ~ 56 行
const addListener = EventTarget.prototype.addEventListener;
DOC.addEventListener = function (type, ...args) {
    if (type === "DOMContentLoaded" && DOC.readyState !== "loading") return args[0]();
    addListener.call(this, type, ...args);
};

这段代码最初是为了少部分客户端下脚本注入执行被（未知原因）延迟导致未执行生效做的兼容，以下是一些解决方案：

  • 尝试删除上述劫持代码，绝大部分客户端都能正常注入执行脚本
  • 前往脚本管理扩展（如 Tampermonkey）管理页点击脚本设置 包括/排除
  • 等待下次推送更新修复此项
