WebGL Webcam light keeps enabled after stoping WebCamTexture

I'm using the following script to enable/disable the webcam on WebGL.

It works fine on the Editor but on the browser, the webcam light stays on after disabling the WebcamTexture.

It happens on Chrome and Firefox.

Any ideas?

Thanks.

 public void Enable()
 {
     #if UNITY_EDITOR || DEVELOPMENT_BUILD
     Debug.Log("Enable");
     #endif
 
     _enabled = true;
 }
 
 public void Disable()
 {
     #if UNITY_EDITOR || DEVELOPMENT_BUILD
     Debug.Log("Disable");
     #endif
 
     _enabled = false;
 }
 
 #region MONOBEHAVIOUR
 
 void Update()
 {
     if(_enabled)
     {
         if(_webcamTexture == null)
         {
             while(!Application.RequestUserAuthorization(UserAuthorization.WebCam).isDone)
             {
                 return;
             }
 
             if (Application.HasUserAuthorization(UserAuthorization.WebCam)) 
             {
                 #if UNITY_EDITOR || DEVELOPMENT_BUILD
                 Debug.Log("Webcam authorized");
                 #endif
 
                 _webcamTexture = new WebCamTexture (WebCamTexture.devices[0].name);
                 _webcamTexture.Play (); 
             } 
             else 
             {
                 #if UNITY_EDITOR || DEVELOPMENT_BUILD
                 Debug.Log("Webcam NOT authorized");
                 #endif
             }   
         }
         else if (_webcamTexture.isPlaying)
         {
             if(!_ready)
             {
                 if (_webcamTexture.width < 100)
                 {
                     return;
                 }
 
                 _ready = true;
             }
 
             if(_webcamTexture.didUpdateThisFrame)
             {
                 _aspectRatioFitter.aspectRatio =  (float)_webcamTexture.width / (float)_webcamTexture.height;
 
                 _imageRectTransform.localEulerAngles = new Vector3 (0, 0, -_webcamTexture.videoRotationAngle);
 
                 _image.texture = _webcamTexture;
             }
         }
     }
     else 
     {
         if(_webcamTexture != null) 
         {
             _webcamTexture.Stop ();
