Yes, I read that. But as I was not seeing this happen, I wanted to
understand why. I was wrongly assuming set-text-properties was not
changing them, but if I understand your message it does change them, but
they are changed back because of font-lock.

Is there a way to change the face that plays well with font-lock? I
tried `font-lock-append-text-property' but it did not work.

Thanks,
