Missing color-convert

[RowanDZ]

presets/packages/preset-ie11/src/index.ts

Line 39 in adbfff1

const include = /[\\/]node_modules[\\/](@storybook\/node-logger|are-you-es5|better-opn|boxen|chalk|commander|find-cache-dir|find-up|fs-extra|json5|node-fetch|pkg-dir|resolve-from|semver)/;

After a lot of swearing, headaches etc, figured out that Storybook 6.3.0-rc11 contained code originally from color-convert, which is not transpiled/has no es5. I copied this file, added color-convert to the include, made it es5 and added locally to our Storybook, and it's finally working again.

const include = /[\\/]node_modules[\\/](@storybook\/node-logger|are-you-es5|better-opn|boxen|chalk|commander|find-cache-dir|find-up|fs-extra|json5|node-fetch|pkg-dir|resolve-from|semver|color-convert)/;

Also, the preset-env gives an error about duplicated presets.

const ie11Preset = [
  '@babel/preset-env',
  {
    targets: {
      ie: '11',
    },
  },
  'SPECIALLY-FOR-IE11',
];

solves that.
