Three.js selectively ignores holes in ExtrudeGeometry, what should I do?

Question

3D

Greetings!
I'm experimenting with Three.js, extruding a shape along the paths:
(here is only a part, the main figure is a hole that is on the screen and which is not)

path.moveTo(193.927, 1036.45);
path.bezierCurveTo(206.093, 1034.95, 218.062, 1038.49, 218.062, 1038.49);
path.bezierCurveTo(226.729, 1027.82, 245.01, 1032.3, 248.396, 1043.99);
path.bezierCurveTo(251.896, 1056.07, 243.729, 1062.16, 243.729, 1062.16);
path.bezierCurveTo(252.396, 1086.99, 230.729, 1103.66, 230.729, 1103.66);
path.bezierCurveTo(230.729, 1103.66, 243.562, 1110.32, 250.229, 1125.66);
path.bezierCurveTo(250.229, 1125.66, 258.396, 1122.82, 264.229, 1133.66);
path.bezierCurveTo(270.062, 1144.49, 264.562, 1153.49, 260.562, 1154.16);
path.bezierCurveTo(256.562, 1154.82, 255.062, 1154.16, 255.062, 1154.16);

The code itself:

simpleShapes = path.toShapes(true);
len1 = simpleShapes.length;
for (j = 0; j < len1; ++j) {
   simpleShape = simpleShapes[j];
   shape3d = new THREE.ExtrudeGeometry(simpleShape, {
      amount: 5,
      bevelEnabled: false
   });		
   
   mesh = THREE.SceneUtils.createMultiMaterialObject(shape3d, [material]);
   mesh.rotation.x = Math.PI;
   mesh.translateX( - 198.611);
   mesh.translateY( - 1118.460);
   group.add(mesh); 
}

The screen itself:

There are no errors in the console. If you squeeze out these holes separately, then everything is there.
What am I doing wrong?
PS I know that there is a separate method for adding holes to a shape, but it doesn't work - you have to manually sort through all the shapes and look at the nesting, which, I think, is insanely long.

Answer 1

In general, judging by the sources, three.js (starting with toShapes: function ( isCCW, noHoles ) { )
the author did not bother with the hierarchy of contours, and did it simply - if the contour is in the contour and the direction is counterclockwise, then a hole, otherwise a new figure.
