Blocking sleep and screen blocking (wake locks) permanently doesn't save

I usually have brave open playing music or video, but still want the computer to turn the screens off. I have an OLED monitor, and making sure it turns off when inactive is very important to prevent burn in. The option to do that is right there, under power management in the system tray. And it does work - brave won't stop the computer from going to sleep or turning off the monitor on it's usual schedule. But even if I choose "every time for this app and reason", as soon as I even reload the tab with those locks, it forgets that setting, and the new wake locks stay active. Is there any way to get that setting to stick? I found some talk about issues saving over a year ago when the feature was being added, but it looks like it was fixed some time ago before the feature was released, so not sure why it's not saving: https://invent.kde.org/plasma/powerdevil/-/merge_requests/363
