   * will be ordered, first by Z-index and then by position. When `undefined`, a `zIndex` of 0 is assumed
   * for layers that are added to the map's `layers` collection, or `Infinity` when the layer's `setMap()`

   * be visible.
   * @property {import("../PluggableMap.js").default} [map] Sets the layer as overlay on a map. The map will not manage
   * this layer in its layers collection, and the layer will be rendered on top. This is useful for
