**Describe the bug (描述问题)**
本意是想点击按钮弹出toast提示，但却一直报错，排查了很久都没找到原因，还望大佬们帮忙看一下，万分感谢

**Steps To Reproduce (重现步骤)**
新建一个路由页面，该页面只有一个按钮，用户点击按钮即弹出toast提示

**Expected behavior (期望的结果是什么)**
正常弹出toast提示

No source file, test, or entry point is named. First reproduce the toast action on a new route using ChatUI 3.0.0, React 19, and Chrome, then capture the actual error and compare it with the expected toast behavior.
