[itxstcom]

• I have searched the issues of this repository and believe that this is not a duplicate.

Version

1.4.10

Environment

chrome、 Notepad、html

Reproduction link

https://www.antdv.com/components/menu-cn/#api

Steps to reproduce

<a-menu @openchange="openchange" mode="inline">在vscode node.js环境下是有效的，但是如果我是网页直接引用antd.js 网址就事件就无效，改成<a-menu @Open-Change="openchange" mode="inline"> 仍然无效。

vue.js:640 [Vue tip]: Event "openchange" is emitted in component but the handler is registered for "openChange". Note that HTML attributes are case-insensitive and you cannot use v-on to listen to camelCase events when using in-DOM templates. You should probably use "open-change" instead of "openChange".

What is expected?

There should be no problem

What is actually happening?

invalid
