First particle does not respect particle systems' forward if that system has moved and rotated

I've got a weird bug:
I'm using single particle system to emit particles from multiple points. And if that particle system has moved, first emitted particle does not respect particle systems forward alignment correctly (even if the X rotation is the same in both cases). See gif:

Spoiler: Gif

Is this a bug, or am I missing something?
Here's a code to test this:

Code (CSharp):

1. using UnityEngine;
2.  
3. [RequireComponent(typeof(ParticleSystem))]
4. public class ParticleEmitTest : MonoBehaviour {
5.     [SerializeField]
6.     private Transform _pointA = default;
7.  
8.     [SerializeField]
9.     private Transform _pointB = default;
10.  
11.     [SerializeField]
12.     private ParticleSystem _ps = default;
13.  
14.     [SerializeField]
15.     private Transform _transform = default;
16.  
17.     private void Update() {
18.         if (Input.GetMouseButtonDown(0)) {
19.             EmitFrom(_pointA);
20.         }
21.  
22.         if (Input.GetMouseButtonDown(1)) {
23.             EmitFrom(_pointB);
24.         }
25.     }
26.  
27.     private void EmitFrom(Transform point) {
28.         _transform.SetPositionAndRotation(point.position, point.rotation);
29.  
30.         ParticleSystem.EmitParams emitParams = new ParticleSystem.EmitParams();
31.         emitParams.applyShapeToPosition = true;
32.         emitParams.position = point.position;
33.  
34.         _ps.Emit(emitParams, 1);
35.     }
36.  
37. #if UNITY_EDITOR
38.     protected virtual void OnValidate() {
39.         _ps = GetComponent<ParticleSystem>();
40.         _transform = transform;
41.     }
42. #endif
43. }
44.  

Just in case, submitted repro - case 1181119.

 

Yes, that does seems to work.
Here's a workaround (if anyone needs it):

Code (CSharp):

1.  
2.     private void EmitFrom(Transform point) {
3.         _transform.SetPositionAndRotation(Vector3.zero, Quaternion.identity);
4.      
5.         ParticleSystem.ShapeModule shapeModule = _ps.shape;
6.         Vector3 position = point.position;
7.      
8.         shapeModule.position = position;
9.         shapeModule.rotation = point.rotation.eulerAngles;
10.  
11.         ParticleSystem.EmitParams emitParams = new ParticleSystem.EmitParams();
12.         emitParams.applyShapeToPosition = true;
13.  
14.         _ps.Emit(emitParams, 1);
15.     }
16.
