Bug description

When right-clicking a directory using Nemo, then selecting the Properties ... Permissions option, it is not possible to change group ownership of files in a directory.

Steps to reproduce

1. Create a test directory with some files.

./TestDir:
total 8
drwxrwxr-x 2 clem clem 4096 Mar 12 11:34 .
drwxrwxr-x 5 clem clem 4096 Mar 12 11:33 ..
-rw-rw-r-- 1 clem clem 0 Mar 12 11:34 testfile-1.txt
-rw-rw-r-- 1 clem clem 0 Mar 12 11:34 testfile-2.txt
-rw-rw-r-- 1 clem clem 0 Mar 12 11:34 testfile-3.txt

2. Change the group.

./TestDir:
total 8
drwxrwxr-x 2 clem shared 4096 Mar 12 11:34 .
drwxrwxr-x 5 clem clem 4096 Mar 12 11:33 ..
-rw-rw-r-- 1 clem shared 0 Mar 12 11:34 testfile-1.txt
-rw-rw-r-- 1 clem shared 0 Mar 12 11:34 testfile-2.txt
-rw-rw-r-- 1 clem shared 0 Mar 12 11:34 testfile-3.txt

3. Using Nemo, right-click the directory, select 'Properties' then The 'Permissions' option/tab.

In the Group dropdown list, the group 'shared' will be listed. Change that to 'clem' and click the
'Apply Permissions to Enclosed Files' button. The expectation here is that the group should be changed back to 'clem', but it remains as 'shared'.

./TestDir:
total 8
drwxrwxr-x 2 clem clem 4096 Mar 12 11:34 .
drwxrwxr-x 5 clem clem 4096 Mar 12 11:33 ..
-rw-rw-r-- 1 clem shared 0 Mar 12 11:34 testfile-1.txt
-rw-rw-r-- 1 clem shared 0 Mar 12 11:34 testfile-2.txt
-rw-rw-r-- 1 clem shared 0 Mar 12 11:34 testfile-3.txt

Note that the directory group is changed.

Expected behavior

It should be possible to propogate group changes using the interface without having to use the terminal.

Additional information

The issue is present in the 6.6.3 version of Nemo which includes the bugfix detailed in bug report #3730/#3731.

The only obvious workaround is to modify the group via a terminal session.

Reproduce the problem in Nemo 6.6.3 on Linux Mint 22.2 using the listed directory and group changes. Start at the Permissions option and the “Apply Permissions to Enclosed Files” action, then trace how group ownership is propagated. Done means the interface changes the group of both the selected directory and its enclosed files without requiring the terminal.
