screenlocker turns off the screen after 60 seconds and then turns it back on
again

I have two monitors, and I set turn off screen after 60 seconds when screen
locked in systemsettings, however I found that when the screenlocker turns off
screen, after 10 seconds, it turns on again, and 60 seconds after that, it
turns off again...

And when I turned off my second monitor, after the screenlocker turned off the
only screen, it would not turn on the only screen anymore.

I thought that might be, when the screenlocker turns off two monitors, the
external monitor(with HDMI connected) counts down for 10 seconds and then
sleep, after that, KDE detect the external screen is detached, it thought that
might be a sign of someone trying to unlock, and then KDE screenlocker turns
off both the two monitors.

STEPS TO REPRODUCE
1. set turn off monitor after specific time when screen locks
2. plug in your second monitor and then lock the screen
3. wait for two monitors to turn off

EXPECTED RESULT

the monitors will not be turned on until you tap some key or move the mouse
