Total Size in stats is not correct when backup is compressed

[FATruden]

Output of restic version

./restic2 version
restic 0.13.1-dev (compiled manually) compiled with go1.18 on linux/amd64

I have built current master with compression support.

How did you run restic exactly?

./restic2 --verbose -r /mnt/restic/repo2/ stats --mode raw-data

enter password for repository:
repository 193651e2 opened (repo version 2) successfully, password is correct
scanning...
Stats in raw-data mode:
Snapshots processed:   1
   Total Blob Count:   97646
         Total Size:   174.626 GiB

What backend/server/service did you use to store the repository?

local dir

Expected behavior

After backup with compression, i can see actual size which is smaller then in 'stats' output:

du -sh /mnt/restic/repo2
99G	/mnt/restic/repo2

Steps to reproduce the behavior

Backup something with compression and check 'stats' in 'raw-data' mode.
