Soucemaps are incorrect

[taoeffect]

It generates entries like this in the css file:

/*# sourceMappingURL=Navigation.vue.map */.modal-card-body[data-v-ccffbe84] {
  padding-top: 0;
}

However, there are several problems:

1. Navigation.vue.map might be in a different folder
2. Navigation.vue.map doesn't exist
3. In the event it does exist, it's called Navigation-[hash].js.map

I'm not actively using this module anymore and don't know how to fix the sourcemaps. PR welcome!
