Particle system BUG???

Hi all. I have an particle system with sizeOverLifeTime param enabled. When I'm trying to emit particles and change their size using script it does nothing, even if I disable sizeOverLifeTime inside script. But if sizeOverLifeTime was disabled from the beginning everything works fine. What is the problem with sizeOverLifeTime parameter? Script:

 public class Test : MonoBehaviour {
 public bool trigger;
 public ParticleSystem m_System;
 ParticleSystem.Particle[] m_Particles;
 // Use this for initialization
 void Start () {

     
 }
 
 // Update is called once per frame
 void Update () {
     if (Input.GetKeyDown("space"))
     {
         
         var sizeOverLifeTime = m_System.sizeOverLifetime;
         sizeOverLifeTime.enabled = false;

         m_System.Clear();           

         m_System.Emit(2000);
         
         m_Particles = new ParticleSystem.Particle[2000];
         var particles = m_System.GetParticles(m_Particles);
         for (int i = 0; i < 1500; i++)
         {
             m_Particles[i].angularVelocity = 0;
             m_Particles[i].startSize = 10;

         }
        m_System.SetParticles(m_Particles, particles);
        m_System.Play();
     }
   
 }
 }
