Displaying the cursor as crosshair on the map

[iem5]

For the building-a-geospatial-app tutorial, I found that on the website the cursor displayed as a crosshair over the map but with the code from the tutorial, it displayed as a hand on both of my browsers. In order to fix that I added:
style={{cursor: 'crosshair'}}
to the end of the DeckGL tag in the return statement of the deckgl-overlay.js file.
