Does not support "extends"

[ca0v]

Here is an example which provides "@extends":

 * @classdesc
 * The map is the core component of OpenLayers. For a map to render, a view,
 * one or more layers, and a target container are needed:
 *
 *     var map = new ol.Map({
 *       view: new ol.View({
 *         center: [0, 0],
 *         zoom: 1
 *       }),
 *       layers: [
 *         new ol.layer.Tile({
 *           source: new ol.source.MapQuest({layer: 'osm'})
 *         })
 *       ],
 *       target: 'map'
 *     });
 *
 * The above snippet creates a map using a {@link ol.layer.Tile} to display
 * {@link ol.source.MapQuest} OSM data and render it to a DOM element with the
 * id `map`.
 *
 * The constructor places a viewport container (with CSS class name
 * `ol-viewport`) in the target element (see `getViewport()`), and then two
 * further elements within the viewport: one with CSS class name
 * `ol-overlaycontainer-stopevent` for controls and some overlays, and one with
 * CSS class name `ol-overlaycontainer` for other overlays (see the `stopEvent`
 * option of {@link ol.Overlay} for the difference). The map itself is placed in
 * a further element within the viewport, either DOM or Canvas, depending on the
 * renderer.
 *
 * @constructor
 * @extends {ol.Object}
 * @param {olx.MapOptions} options Map options.
 * @fires ol.MapBrowserEvent
 * @fires ol.MapEvent
 * @fires ol.render.Event#postcompose
 * @fires ol.render.Event#precompose
 * @api stable

yes, it does support @extends.. i just pasted your code into a file and ran this: (you can see the augments data is present and correct)
