STEPS TO REPRODUCE
1. I am using this device: https://www.key-id.com/fido2-key-with-windows-hello/
2. I have installed pam-u2f: https://github.com/Yubico/pam-u2f.git
3. I configured locking in /etc/pam.d/fingerprint as:
    > auth sufficient pam_u2f.so authfile=/etc/u2f_keys userverification=1 cue

OBSERVED RESULT
When I close the lid of my MSI Raider GE77HX 12UGS to suspend the system, the LED on the fingerprint reader turns on and stays on until I open the lid again to resume the system.

If I remove the device and plug it back in while the system is suspended, the LED does not turn on. However, after opening the lid, the lock screen becomes unresponsive, and I need to unlock the system from TTY.

EXPECTED RESULT
Before KDE 6.3, the LED was only enabled after opening the lid, and everything worked flawlessly. This looks like a regression.
