Notable gaps:

• The following test cases render empty images:
  • contour-infoviz_border_ref
  • simple-mesh-layer-shading-flat
  • simple-mesh-layer-shading-smooth
  • terrain-layer
• ColumnLayer & derivative layers flat mode - fill color is always white fix(layers): ColumnLayer flat mode in webgpu #10535
• H3Layer - top shading is incorrect
• Any tests concerning MercatorViewport wrapping only renders one world copy fix(core): render repeated map viewports correctly with WebGPU #10536
