If the mask contains a alpha channel CopyOpacity does not use it as a
grey scale mask!
That it is a opaque channel exists that is what is copied, just as the
name implies, requiting in bad form of Dst_In composition.
To use CopyOpacity correctly make sure the mask has no
alpha/matte/opaque channel.
