When my computer goes to sleep and bluetooth is turned on, sometimes (not always) when it wakes up bluetooth will be turned off. This doesn’t seem to happen with wifi, which works as I expect, i.e. on/off state is preserved across sleep.
Is this normal or expected, and is there any way to prevent it, such as increasing some timeout option value? The main problem is that I’d like to put my external keyboard on bluetooth, but if this happens I can’t use it to unlock 
But more generally, I’m the type of guy for whom an unreliable or randomly failing feature is worse than none at all, and consequently I had to stop using bluetooth even for other devices.
Environment: System76 Oryx Pro, Pop-OS 22.04 LTS, Gnome 42.9 over X11.
