重现步骤

通过排除法感觉是和页面中jspanel4 有冲突。

脚本猫版本

页面是哪个页面呢？

没有更多信息，无法复现，先close了

重新方法：访问 https://jspanel.de/，创建测试脚本：

// ==UserScript==
// @name         New Userscript
// @namespace    https://bbs.tampermonkey.net.cn/
// @version      0.1.0
// @description  try to take over the world!
// @author       You
// @match        https://jspanel.de/
// @grant        GM_addStyle
// ==/UserScript==

(function() {
    'use strict';
    GM_addStyle(`
        body { background: #f0f0f0; }
        .btn { color: red; }
    `);
    // Your code here...
})();

感谢反馈，已复现，我看看

🐛 增强消息类型判断 #676

不知道这个网站干了什么，ev instanceof MouseEvent为true，导致脚本猫的一个逻辑错误的，现已修复：https://github.com/scriptscat/scriptcat/actions/runs/17545510510

let ev=new CustomEvent("test", {
      code:0,
    });
console.log(ev instanceof CustomEvent, ev instanceof MouseEvent)
