Immediate mode Draw.Line not appearing in standalone build.

I am attempting to use the new ImmediateModeShapeDrawer to compare drawing a parametric curve in immediate mode using Draw.Polyline and Draw.Line respectively.

While both approaches work in the editor's Game View, Draw.Line calls do not appear to work in a standalone build:

(Left is standalone build, right is editor Game view).

The complete test code is as follows:

using Shapes;
using UnityEngine;

[ExecuteAlways]
public class ShapesLineTest : ImmediateModeShapeDrawer
{
    public bool usePolyLine;
    public Color color = Color.red;
    
    const float thickness = 0.2f;
    const int count = 128;

    public override void DrawShapes(Camera cam)
    {
        using (Draw.Command(cam)) 
        using(PolylinePath polyPath = new PolylinePath())
        {
            for (int i = 0; i < count + 1; ++i)
            {
                float param01 = i / (float)count;
                Vector3 point = GetPoint(param01);
                polyPath.AddPoint(point);
            }
            
            Draw.ResetAllDrawStates();
            Draw.Matrix = transform.localToWorldMatrix;
            Draw.BlendMode = ShapesBlendMode.Opaque;
            Draw.LineGeometry = LineGeometry.Volumetric3D;
            Draw.LineThicknessSpace = ThicknessSpace.Meters;
            Draw.LineThickness = 1;
            
            if (usePolyLine)
            {
                Draw.Polyline(polyPath, closed: false, thickness: thickness, color: color);
            }
            else
            {
                Vector3 lastPoint = polyPath[0].point;
                for (int i = 1; i < polyPath.Count; ++i)
                {
                    Vector3 curPoint = polyPath[i].point;
                    Draw.Line(lastPoint, curPoint, thickness, color);
                    lastPoint = curPoint;
                }
            }
        }
    }
    
    private static Vector3 GetPoint(float param01)
    {
        float param = Mathf.Lerp(-Mathf.PI, Mathf.PI, param01);
        return new Vector3(param, Mathf.Sin(param * 2), 0);
    }
}

Is there a reason why Draw.Line calls might not be showing up for me in a standalone build, while Draw.Polyline calls are? This is a test project that only contains this code and I have not changed any Shapes settings from their defaults. The camera is unchanged except for its clear mode being set to color instead of Skybox.

I used the examples on https://acegikmo.com/shapes/docs/#immediate-mode and was unable to find anything there that might explain this behavior, but I'm hoping I just missed something obvious.

Best,
