Latest 8 and 9 images does not seem to have a sticky bit for /tmp

Description

I can't figure out why, but it looks like latest rockylinux/rockylinux:8 and rockylinux/rockylinux:9 do not have a sticky bit positionned on /tmp.

What I've observed

Investigations

I've quickly looked at the various layer.tar.xz files and It seems that the sticky bit is there.

I don't really understand where it can disappear :shrug: Any help would be really appreciated.
