Esri/heatmap-layer-js won't display across dateline

[Anonymous User]

I'm using the Esri/heatmap-layer-js  by Matt Driscoll and have noticed that it does not render across the international dateline. 

To see this behavior in the sample, zoom out from San Francisco to the world and pan west or east across the dateline and continue to San Francisco.  In Firebug I can see the data is being queried, but it simply is not being rendered.

Is this expected behavior?  In my use case I have world wide data (v.s. a small area like San Francisco) so need to have continuous display across the dateline.

Yes, I think the failure to normalize the extent is playing a part in both situations.

I've noticed that the esri/geometry/webMercatorUtils module can be used to normalize geometries by converting them from web mercator to geographic and then back again.  Normalization appears to be included. 

webMercatorUtils.geographicToWebMercator((webMercatorUtils.webMercatorToGeographic(map.extent)));
