Regex support for pattern attribute

[baidario]

I'm submitting a bug report

Webpack version: 3.0.0
HTML-Loader version: 0.4.5
Please tell us about your environment: Windows 10

Current behavior:
I use angularjs, and some inputs has ng-pattern attribute. html-loader remove backslashes in regex inside this attribute and because of this regex not valid.
In my code I have ng-pattern="/^\+[\d]{7,15}$/" and output is

Expected/desired behavior:
Please, add regex processing

Loader config

{
  test: /\.html$/, 
  use: [
    {
      loader: 'html-loader',
      options: {
        minimize: true,
        removeComments: true,
        collapseWhitespace: true,
        interpolate: true
      }
    }
  ]
}

Does this also happen without minimize: true? It's likely related to html-minifier

[baidario]

This behavior not depend on minimize option

Is the interpolate: true option
