`templateParameters` not working when running in webpack dev server with `output.publicPath` specified

[SevenOutman]

Current behaviour 💣

When output.publicPath is specified in webpack configuration and running webpack dev server, the html-webpack-plugin won't populate template parameter placeholders in the template file.

Expected behaviour ☀️

Template parameters getting populated correctly.

@SevenOutman That is a funny situation, there is no bugs, by default we have static: "/public/" directory for static files, but you have the interpolated HTML file in dist and index.html template in static, so dev server handle public/index.html, but it is a template, so just set (you can use CLI - --static ./dist):

devServer: {
  static: path.resolve(__dirname, "dist")
},

We even have:

<i> [webpack-dev-server] Content not from webpack is served from '/home/akait/IdeaProjects/html-webpack-plugin-template-parameter-repro/public' directory

😄

I'll see if it works for me later, thanks!
