If there are pending interrupts before getting hibernate mode, they would keep and be stored until wake-up.
However such operation which is maintained interrupts during hibernate mode is unexpected, so it might have something wrong with interrupts or wake-up.
It's recommended to clear all pending interrupt before entering into Deep sleep/ Hibernate mode.
We try to clear and confirm all pending interrupts before going into hibernate mode.
I've tried various test circuits, but it may be important to clear all interrupts.
However, this phenomenon is due to multiple factors.
It is difficult to solve by just clearing all these interrupts.
