Power button used for both suspend and wake up: device suspends again right after waking up

I have a Lenovo Duet 3 with PostmarketOS 24.12 aarch64, GNOME 47 and openRC. The tablet has a power button which suspends the tablet to RAM when pressed, but when the tablet is suspended it is also the only button to wake it up, if we ignore the detachable keyboard. The issue is that the press of the button during the sleep results in the keypress event being propagated to the system as soon as the tablet wakes up, which then goes to sleep again right after. This is the output of evtest right after I pressed the power button in order to suspend and then wake up right after:
