Research direction
Reproduce the behavior with the provided xset commands on the Raspberry Pi 4 system described, and inspect dmesg while the display blanks. Compare the current Bullseye behavior with the reported Stretch behavior and the hdmi_blanking and disable_dpms settings in /boot/config.txt. Done means the display becomes blank without stopping its signal to the TV.

Description
Describe the bug
On Stretch, I had my Pi configured to blank the display, but still send a display signal. I'm using a TV for a display and if it looses the display signal, it turns off completely and is a pain to get set back up again.
I just installed Bullseye and now, whenever the display is blanked, the display signal stops as well.
Steps to reproduce the behaviour
xset s blank
xset s 5
xset -dpms
Then wait 5 seconds.
I also tried adding:
hdmi_blanking=0
disable_dpms=1
to /boot/config.txt, but it doesn't help.
