IE11下提示：Cannot redefine non-configurable property 'currentScript'

[SamirGuo]

What happens?

在IE11下，如果在qiankun执行前引入过currentScript的polyfill，则会出现：Cannot redefine non-configurable property 'currentScript'

qiankun/src/sandbox/patchers/dynamicAppend/common.ts

Line 222 in 4e3e36c

Object.defineProperty(document, 'currentScript', {

Mini Showcase Repository(REQUIRED)

`
if (!(('currentScript' in document))) {
Object.defineProperty(document, 'currentScript', get: function() { ... });
}
import { registerMicroApps, start } from "qiankun";

...
start();
`

Context

• qiankun Version: 2.4.0
• Platform Version: Windows 10
• Browser Version: IE 11（正式版本） （64 位）
