Long cells disappear too early #1181

I use very long tables. And now I noticed an unpleasant bug. I used MultiGrid and too long cells disappear from the screen before they go beyond its border. I was trying to set up using overscanColumnCount and overscanRowCount but it didn't work.

I found that the default values for overscanColumnCount & overscanIndicesGetter aren't being set. So a grid is only rendering what cells are visible (no overscan). Adding the props with the default values correctly adds overscan elements.

Thanks @bradwoods - setting those defaults solved the issue for me
