Support IE 11 using browserslist and babel

I already have this in my .babelrc:

  presets: [
    [
      'env',
      {
        targets: {
          browsers:   'last 2 versions, > 5%'
        },
        modules:      false,
        useBuiltIns:  'entry',
        debug:        true
      }
    ]
  ]

Now I want to support IE 11 too. So I added IE 11 to the browsers string. But when I test it I still see an error related to custom events for example. Adding a polyfill for it, fixes it. But then I'm seeing another error.

When I run the script I'm seeing:

Using targets:
{
  "chrome": "65",
  "android": "4.4.3",
  "edge": "16",
  "firefox": "59",
  "ie": "10",
  "ios": "11",
  "safari": "11"
}

I don't want to manually add polyfills for each feature. Anyone knows if adding IE 11 to the browsers string should fix it?

So you force ie to be 11 or higher while all o
