HSV Threshold Mask output is labeled as IMAGE but it's MASK

[scruffynerf]

class HSVThresholdMask:
    ...
    RETURN_TYPES = ("IMAGE",)
    ...

    def hsv_threshold(self, image: torch.Tensor, low_threshold: float, high_threshold: float, hsv_channel: str):
     ...
            mask = cv2.inRange(hsv_image[:, :, channel], low_threshold, high_threshold)
            tensor = torch.from_numpy(mask).float() / 255.
            result[b] = tensor
        return (result,)

is this supposed to return a Mask or an Image? it's not a proper Image.
