cannot select basemap in Basemap gallery

[ADITYAKUMAR1]

Hi,

  I am using ArcGIS JavaScript 4 and I have added base map gallery widget to my application. I had my own container which I added to the gallery. But after adding the widget I am not able to select any layer inside the widget.

I followed the ESRI example to add a widget and there also same problem exist.

https://developers.arcgis.com/javascript/latest/sample-code/sandbox/?sample=widgets-expand

Is this a problem from ESRI side? Has anyone else encountered this problem?

Thanks
