Minimal reproduction

It’s a private repo and haven’t had chance to do this yet but the plugin config looks like this:

    new SVGSpritemapPlugin('path/to/files/*.svg', {
      output: {
        filename: '../../path/to/output/sprite.svg',
        svg4everybody: true,
        svgo: true
      },
      sprite: {
        generate: {
          title: false
        },
        prefix: false
      }
    })

If necessary, I can try and recreate this in a repo 🙂
