htp411 opened a new issue, #21273: URL: https://github.com/apache/echarts/issues/21273
### Version 5.4.1 ### Link to Minimal Reproduction https://codesandbox.io/p/sandbox/5gzlw7 ### Steps to Reproduce 1. 自定义Map ` function Map() { } ` 2. 第一步创建的Map对象能够通过 typeof Map === 'function' 的验证 <img width="3586" height="1970" alt="Image" src="https://github.com/user-attachments/assets/24e569b9-240d-4bd8-a1d2-b876aac14ec9"; /> ### Current Behavior 使用更为严格的方式判断当前作用域的Map是不是原生的Map ` const isNativeMap = () => typeof Map === 'function' && Map.toString().replaceAll(' ', '').replaceAll('\n', '') === 'functionMap(){[nativecode]}'; ` ### Expected Behavior 在全局引入Echarts的情况下，只有当前作用域的Map是原生的Map时，才用 new Map创建实例，其余情况还是用Echarts自带的 ### Environment ```markdown - OS: Mac OS - Browser: Chrome - Framework: ``` ### Any additional comments? _No response_ -- This is an automated message from the Apache Git Service.
