Kibana won't load on IE

[LeeDr]

Kibana version: 7.1.0 (7.x branch snapshot)

Elasticsearch version: 7.1.0 (7.x branch snapshot)

Server OS version: Ubuntu 14

Browser version: IE11

Browser OS version: Windows 10

Original install method (e.g. download page, yum, from source, etc.): tar.gz files (default distribution with security enabled)

Describe the bug: My understanding was that in 7.x Kibana would have an error or warning about insecure browser on IE11.
And in master with default settings it would not load (but you could bypass by setting csp.strict: false on master and keep using IE11).

But I could be wrong on that ^?

Steps to reproduce:

1. Try Kibana from 7.x branch (currently 7.1.0) on IE11
   It never loads. Just shows;

For the sake of triage, I'm making an educated guess that this is an issue with our polyfills or babel configuration. @elastic/kibana-operations can someone look into this?

[epixa]

I think this may be related to #33093, which changed babel in big ways and only exists in 7.x onward.

@epixa I've found the problem. It's not related with the changes made on Babel #33093 at all. It was caused by this PR #35548

Basically it has updated to [email protected] which in dependencies of dependencies updates ends up with a [email protected] in the browser. That dependency is a node_module that is not distributed with ES5 so unsupported ES6 code endups inside the DLL which causes trouble in IE 11.

Should I backport the fix both for master and 7.x?

@mistic Yes, please

@Susmit07 the problem you're having doesn't have anything to do with the one reported on that issue. It seems to me a bad configuration on your docker setup.

As a matter of an example for testing purposes try to run the kibana docker using (https://www.elastic.co/guide/en/kibana/current/docker.html#_running_kibana_on_docker_for_development):

docker run --link YOUR_ELASTICSEARCH_CONTAINER_NAME_OR_ID:elasticsearch -p 5601:5601 {docker-repo}:{version}
