EXTI lineX is automatically disabled.

[HAPPYDAY]

1. Select STM32MP151A

2. Select an GPIOx and set to GIPIO_EXTx

3.Select again GPIO under Pinout View, right click -> Pin Reserved -> Cortex-M4

4. Goto NVIC: EXTI lineX interrupt Enable Check.

5. Select any of the peripheral devices, enable Cortex-A7 or Cortex-M4, and disable it.

6. Goto NVIC: The enabled EXTI lineX is automatically changed to disable.

And Pin Reserved for the corresponding pin is automatically changed from Cortex-M4 to Free.

It is very inconvenient that the set EXTI is all initialized due to the above phenomenon.

Is the way I proceeded wrong? Or maybe it's a STM32CubeIDE(1.6.0) bug. Please check.
