+{-| `point` is the coordinates in pixels in screen space.
+
+`lngLat` is the coordinates as a longitude, latitude in geographic space.
+
+`renderedFeatures` is a geojson that intersect the `lngLat`:
+
+The properties value of each returned feature object contains the properties of its source feature. For GeoJSON sources, only string and numeric property values are supported (i.e. null, Array, and Object values are not supported).
+
+Each feature includes a top-level layer property whose value is an object representing the style layer to which the feature belongs. Layout and paint properties in this object contain values which are fully evaluated for the given zoom level and feature.
+
+Features from layers whose visibility property is "none", or from layers whose zoom range excludes the current zoom level are not included. Symbol features that have been hidden due to text or icon collision are not included. Features from all other layers are included, including features that may have no visible contribution to the rendered result; for example, because the layer's opacity or color alpha component is set to 0.
+
+The topmost rendered feature appears first in the returned array, and subsequent features are sorted by descending z-order. Features that are rendered multiple times (due to wrapping across the antimeridian at low zoom levels) are returned only once (though subject to the following caveat).
+
+Because features come from tiled vector data or GeoJSON data that is converted to tiles internally, feature geometries may be split or duplicated across tile boundaries and, as a result, features may appear multiple times in query results. For example, suppose there is a highway running through the bounding rectangle of a query. The results of the query will be those parts of the highway that lie within the map tiles covering the bounding rectangle, even if the highway extends into other tiles, and the portion of the highway within each map tile will be returned as a separate feature. Similarly, a point feature near a tile boundary may appear in multiple tiles due to tile buffering.

For this reason we allow controlled mode where no event handlers are attached, but you need to feed the element its state. So it's up to you to implement all the user interactions.
