No password required after hibernate despite lock settings enabled

System Information:

• Linux Mint: 22.1 (xia)
• Kernel: 6.8.0-57-generic
• Cinnamon: 6.4.8
• Desktop Environment: Cinnamon

Issue:
When returning from hibernate, the system does not require authentication despite having the following security settings enabled:

• org.cinnamon.desktop.screensaver lock-enabled = true
• org.cinnamon.settings-daemon.plugins.power lock-on-suspend = true
• org.cinnamon.desktop.screensaver idle-activation-enabled = true

Expected Behavior:

• System should require password authentication when returning from hibernate
• This is a basic security feature that should work by default

Actual Behavior:

• System returns from hibernate without requesting authentication
• Screen lock settings appear to be ignored during the hibernate/resume cycle

Security Impact:
This is a security concern as anyone can access the system and all open applications after hibernate without authentication.

Steps to Reproduce:

1. Configure screen lock settings as listed above
2. Hibernate the system
3. Wake the system
4. Observe that no password is required to access the desktop

Additional Notes:

• Manual screen locking works correctly (using dm-tool lock or Ctrl+Alt+L)
• Screen lock works properly for screen timeout
• Only the hibernate-resume cycle appears to bypass the lock screen

Start by reproducing the hibernate and resume cycle with the listed Cinnamon screensaver and power settings, then inspect how Cinnamon handles lock-on-suspend compared with manual locking via dm-tool lock or Ctrl+Alt+L. Done means resume consistently requires authentication while timeout and manual locking continue to work.
