Errors in IE11 when importing polyfills using es-abstract.
See original GitHub issueIs this a bug report?
Yes
If you import react-app-polyfill/ie11 before importing any shim/polyfill using es-abstract lib, you get an error in IE11 (possibly other browsers as well). Some example polyfills: object.entries, array-includes, object.values
Error: object doesn't support property or method Symbol(Symbol.iterator).9_<some-hash>
Location: es-abstract -> GetIntrinsic.js at line 56.
Workaround: import react-app-polyfill/ie11 after importing all shims/polyfills using es-abstract.
Environment
IE11, presumably anything IE.
Steps to Reproduce
- Create new app
- in index.js, on line 1,
import react-app-polyfill/ie11 - in index.js, on line 2,
import objectValues from 'object.values/polyfill' - Open your app in IE11.
Expected Behavior
App would run.
Actual Behavior
App crashes.

I am seeing the same issue. I have started using @babel/polyfill instead as a workaround.
I also have this issue thanks to
react-app-polyfill/ie11’s Symbol polyfill making my app not work in IE 11.
