Visualization map (markers) doesn't reset with data

Issue Summary

When I use a query filter to narrow down some geo data, the map view doesn't reset to line up with the map markers currently being displayed. The viewbox on the map stays wrapped around the first set of data (even after it disappears). So I have to zoom and drag the map manually to see the data.

Steps to Reproduce

1. Load this data set from gh and then manipulate it with the Query Results data source.
2. Use a query filter to limit the data by state name
3. Make a map (markers) visualization
4. Change the query filter
5. Observe that the the map visualization doesn't update with a different data set.

I would expect the map to update its viewport to wrap around the most recently rendered coordiantes.
