mdi removed

Hi,

i'm using vue and mdi with this config:

new PurifyCSSPlugin({
    paths: glob.sync([
      path.join(__dirname, "./src/index.html"),
      path.join(__dirname, "./src/**/*.vue"),
      path.join(__dirname, "./src/**/*.js")
    ])
  })

Something importing mdi is rejected by the plugin so I can't see my icons.
I already tried listing all rejected css properties, but nothing looks like mdi.
