tail -F not working as expected

[hksdpc255]

My understanding is that tail -F should reprint the entire contents of a file from the beginning when the file is recreated. The current behavior does not appear to do this:

Terminal 1

$ tail -F testfile.txt
abc
ghi

Terminal 2

$ echo abc > testfile.txt
$ echo def > testfile.txt
$ echo ghi >> testfile.txt

Expected terminal 1

$ tail -F testfile.txt
abc
def
ghi

I am not sure whether this is an issue with this project or with an upstream component. Additionally, I am running Chimera Linux from within a Podman container on Fedora 42 Silverblue.

Another example

Terminal 1

$ tail -F testfile.txt
abc
ghi

Terminal 2

$ echo abc > testfile.txt
$ echo def > testfile.txt
$ echo ghi >> testfile.txt
$ echo jkl > testfile.txt
$ echo mno >> testfile.txt

Terminal 1 from Fedora

$ tail -F testfile.txt
abc
ghi
tail: /tmp/test: file truncated
jkl
nmo

I see the same behaviour in Chimera (not in container) and a 14.1-RELEASE VM. Turns out there's an open bug upstream:
