Unity WebGl does not free webcam when stopped

Good time of day, I want to make an image using the webcam. When I take image, call method texture.Stop(); but the camera is not freed anyway (white light is on). All work right in other platforms.

How to shut down a camera in WebGL?

The code method it taked image.

private void OnCaptureTake()
{
if (_captureImage.texture != null)
{
((WebCamTexture)_captureImage.texture).Stop();
OnTakeTexture.SafeInvoke(_captureImage);
isOnClick = false;
_takeCaptureButton.SetActive(false);
_captureImage.gameObject.SetActive(false);
}
}
