Datasets with large geo data inside

```mathematica
ResourceData["Anthropogenic Biome"][Select[MatchQ[#Class, "Rangelands"]&]][All, {#Biome, #Color, #Polygon[DateObject[{1700}, "Year"]]} &] // Normal;
%[[1]]
```

but in `Dataset` form it does not work and hands the frontend

```mathematica
ResourceData["Anthropogenic Biome"][Select[MatchQ[#Class, "Rangelands"]&]][All, {#Biome, #Color, #Polygon[DateObject[{1700}, "Year"]]} &]
```
