Blacklineing an image in PDF won't remove below content in version 1.22.2

[bbustamante]

Hello,
I have just updated my PyMuPDF version from 1.21.1 to 1.22.2. When I blackline a text from an image even wen I edit the result PDF to get de blankline from the file manualy, the text behind it was desaparead (that's, for me, the correct working system). But right now, when I do it the text is still there. This just happend when the text is an image inside de PDF (second line of the example), not wen is a real text (first line of the example).

I include three (plus one) images with the process and the PDF I use:

1. Te original PDF with two lines. First one is real text while the second one is an image.
   

2. The result PDF after blackileing it with PyMuPDF.
   

3. The result PDF manually edited to remove the blacklines.
   

4. The PDF file I use for the example.
   PyMuPDF example.pdf

5. The result of the example made with PyMuPDF 1.21.1 after editing manually for removing blacklines.
   

Any idea of what is happening? How could I resolve it?
Thanks.
