Use core-js promise polyfill for nomodule browsers #10985

timneutkens · 2020-03-11T17:43:03Z

Also updated to the core-js@3 features modules instead of importing the exact modules directly.

Add tests that does a bad override of Promise:

<script>window.Promise = undefined</script>

Add a test for RegExp issue outlined in NextJS 9.3 polyfills on IE11 break application #10966

Also updated to the core-js@3 features modules instead of importing the exact modules directly. Fixes vercel#10966

Timer

LGTM if IE11 tests pass.

In my case, migration from 9.2.2 to 9.3.0 was impossible until now. I think v9.3.0 has an issue related to polyfill which can be seen in IE11:

But the release v9.3.1-canary.2 solves the problem. Looks like this is because of the following: core-js/modules/* => core-js/features/*. So @timneutkens, thanks for the fast reaction.
