I released the new ProPainter version v.1.2.4

P.S.
If you look in more detail your file "mask.png" (by opening it with PIL and converting it to np.ndarray) you will discover that mask_np.min()=1. So in your file the black is represented by the number 1 and not 0 as should be (while mask_np.max()=255 is correct). This anomaly prevented the filter from correctly recognizing the mask hedges. The new added option will fix also this issue.
