Second related issue

• Load a 3DTileset catalog item in 3D (Cesium) map mode
• Zoom to layer to trigger loading of tiles for view extent
• Switch map mode to 2D (leaflet) while tiles are still loading
• Leaflet basemap does not draw to full extent

E.g. To add a 3DTileset, add the following to the catalog array in TerriaMap/wwwroot/init/simple.json in TerriaMap:

{
  "type": "3d-tiles",
  "name": "Fort Denison",
  "url": "https://nsw.digitaltwin.terria.io/api/v0/data/a99c8280-dbfe-475a-8a4e-3c2d2ca87513/3dtiles/tileset.json",
  "id": "adsfsadfds"
},
