Error: writing blob: archive/tar: write too long

Context: podman @ 6eaa1d55a035b68c8a75031b586addbfde9f1096 on Rawhide with the following /etc/containers/storage.conf:

[storage]
driver = "overlay"
runroot = "/run/containers/storage"
graphroot = "/var/lib/containers/storage"

[storage.options]
pull_options = {enable_partial_images = "true", use_hard_links = "false", ostree_repos="", convert_images = "true"}

[storage.options.overlay]
use_composefs = "true"

composefs-1.0.3-1.fc40.x86_64

I believe this will also reproduce on f39 but don't feel like testing. In containers/podman#22425 it fails f39 and rawhide, local and remote. Does not fail f38 because, my hunch is, that uses vfs instead of overlay.
