ProPainter Vapoursynth filter

In the script "propainter_render.py", there is this code

def model_init(self, torch_device, model_dir: str = None, mpath: str = None):
        self.device = torch_device

        self.img_mask_is_cropped = False

        # load image mask if available
        if mpath is None:
            self.img_mask = None
        else:
            img_m = Image.open(mpath).convert('RGB')
            out_size = img_m.size
            if out_size == self.clip_size:
                self.img_mask = img_m
            else:
                self.img_mask = img_m.resize(self.clip_size)
        self.img_mask_orig = self.img_mask

So if you provide in input mask_small.jpg is resized as the image attached.

So looking to the code there is not difference in providing in input "mask_small.jpg" or "mask_big.png".

In effect using "mask_small.jpg" or "mask_big.png" it works while using "mask.png" it doesn't work, it is very crazy.
The only explanation that I can find is that the mask's edges in "mask.png" are sharper than in "mask_big.png", probably for a proper identification of mask edges it is better to use smooth edges.
