  // this here is a little bit of hackery! we need to mark a few modules in node_modules
  // not to *ignore* them but actually to include them in the transform. Jest doesn't have
  // a transformIncludePattern option, so this is how they recommend you explicitly include
  // code in node_modules. We need to do this because CKEditor code is distributed as ES6
  // modules with some webpack-specific syntax in it. This will ensure it gets transpiled
  // with Babel (this is cached between test runs so it doesn't have too much performance
  // overhead. See here for some details:
