mobx 6 does not support ie11

[MrErHu]

Intended outcome:

When I configure it according to the official website of Mobx

{    
    // Babel >= 7.13.0 (https://babeljs.io/docs/en/assumptions)
    "plugins": [["@babel/plugin-proposal-class-properties"]],
    "assumptions": {
        "setPublicClassFields": false
    }
}

import { configure } from "mobx"

configure({ useProxies: "never" }) 

I think it works fine in IE11

Actual outcome:

starting from mobx6.8 version, mobx reports an error in ie11，the error effect is as follows:

The problem is very similar to this one

res is object type，so throw error. This code was added by babel in mobx

How to reproduce the issue:

When using Mobx 6.8 or later in IE11 the polyfill uses [email protected]

Versions

Mobx 6.8 or later

I don't think the code you are sharing above is coming from Mobx, nor can I read the exception, or reproduce the issue from a screenshot. Given that the linked issue is about Angular, it seems more of an issue with your project setup / babel / core-js, and I'm not sure how this is actionable for us here.
