I'm basically running swayidle timeout 10 "powerctl mem" while the screen is locked.

The first time the system reaches 10s idle, swayidle triggers, runs powerctl mem and puts it to sleep. I then press Return to wake the system up. swayidle doesn't trigger ever again.

I think that the keypress is "swallowed" by the system when asleep, so sway doesn't really know that any keypress happened. I wonder if maybe sway itself should reset the idle timer when woken up from sleep...? I don't think it even knows that this happened TBH.

The end result is that swayidle only triggers the first time. To be sincere, I'm not sure if this is a bug of a case of me using it wrong.
