RP2040 not waking up from dormant mode (external gpio, active low) #40

I am using a nRF24L01+ 2.4GHz transceiver which has an IRQ pin that can fire (active low) when data has been received. Unfortunately, the RP2040 doesn't wake up properly and therefore I cannot process any packets after it goes to dormant mode.
