1.85.0

What happened

On a paged pushdown grid the map asks the engine for the rows inside its view, up to viewportCap. The view held more, and the engine could not bin them into density cells, so the map drew nothing rather than an arbitrary subset.

The fix

Zoom in or narrow the grid's filter, or raise viewportCap.

The smallest fix

viewportCap: 50000
