Bug#1077925: cdimage.debian.org: firmware not listed as installed and wrong user - group

Package: cdimage.debian.org

Dear Maintainer,
 
after installation with debian netinstall iso (12.5 and 12.6), the
following firmware is present: 
ls -lh /lib/firmware/intel 
insgesamt 24K
drwxr-xr-x 4 3064 1199 4,0K 29. Jun 12:20 sof 
drwxr-xr-x 2 3064 1199 20K  6. Jan 2023  sof-tplg 
The files have unknown user and group names and seem to belong to
firmware-sof-signed/stable 2.2.4-1 all which is not listed as
installed: 
apt list firmware-sof-signed 
Auflistung… Fertig
firmware-sof-signed/stable 2.2.4-1 all 

Expected behavier:
the firmware files have correct user and group and
the package is marked as installed 

or 
the files are not present. 

Bye
