Bug: TextLayer rendered behind other layers

I have multiple layers that I pass to my DeckGL component. The last of which is a TextLayer.

Actual Result

The Scatterplot and GeoJsonLayers that preceed the TextLayer in the layers array overlay the TextLayer. The IconLayer which is also passed in after the ScatterplotLayer and GeoJsonLayer is rendered correctly.

Expected Result

As the TextLayer is the last item in the Array, it should be rendered on top of all other layers. So the white text should appear in front of the grey dot and the grey lines.

Code Example

Here’s the generation of the layer array passed to the DeckGL component

return [
      new ScatterplotLayer({
      id: 'grey-dots',
      data: greyDots,
      getPosition: d => d.geometry.coordinates,
      getRadius: 20,
    }),
    new GeoJsonLayer({
      id: 'lines',
      data: lines
      getLineColor: [129, 134, 145],
    }),
      new IconLayer({
        id: 'icon',
        data: markerPoints,
        wrapLongitude: true,
        getIcon: d => 'marker',
        getPosition: d => d.geometry.coordinates,
        getColor: d => getColor(d),
        getSize: d => 5,
        iconAtlas: '/icon-atlas.png',
        iconMapping: {
          marker: {
            x: 0,
            y: 0,
            width: 128,
            height: 128,
            anchorY: 128,
            mask: true,
          },
        },
      }),
      new TextLayer({
        id: 'icon-texts',
        data: texts,
        getText: d => `My Text`,
        getPosition: d => d.geometry.coordinates,
        getColor: d => [256, 256, 256], 
        getSize: d => 20,
        sizeScale: 1,
        getPixelOffset: [0, 15],
      }),
    ];

Is there a bug or am I doing something wrong?

Maybe disable depth testing for the text layer, or add a small Z offset?
