Columbus Map Stretch to Fill

Is it possible to eliminate the black bars on the top and bottom of the Columbus map mode by stretching the map vertically?


I’ve figured out a somewhat hacky solution to this, incase someone needs it:
If you set your viewer’s useDefaultRenderLoop to false, then you can make Cesium render into a fixed-sized viewer, then change the size to fill your window when it’s done. That involves setting up your own callback that runs periodically and putting this code in it:

      const container = self.cesiumBase.viewer.container; = '2000px'; = '1000px';
      self.cesiumBase.viewer.render(); = '100%'; = '100%';
