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.
