[Pkg-javascript-commits] [leaflet-markercluster] 120/479: For mobile set the expanded bounds to just the screen, this means there is only 1/9th the clusters on screen which gives much better performance. During a zoom/drag on mobile the map tiles aren't updating anyway, so this fits with them. Refs #19
