@Justineo I tried to do the suggested fix of adding this to the vue.config.js, however it didn't work.

chainWebpack: config => {
    config.module
      .rule('vue')
      .use('vue-loader')
      .loader('vue-loader')
      .tap(options => {
        options.compilerOptions.preserveWhitespace = true
        return options
      })
  }

      })
  }

It does not work for me. But when i delete return options, it works.

Same here: It only works after removing "return options".
Removing the " .loader('vue-loader')" part doesn't appear to make any difference either
