Modal dialog in IE11 error with V4.1.0

Hi.

I've found an issue with the version 4.1.0 while trying to display a modal dialog in IE11 using jquery.

The error is:

Object.keys: Invalid argument
rollupPluginBabeHelpers

If I use the version 4.0.0 all is ok

I'm not sure if #26291 will fix all issues with modal in IE11.
