Issue description

There are two area2d,we call them A and B, make A can check B. make A's area_enter connect to a function to observe.

When they are overlaping, turn A' monitoring(true -> false -> true), A' area_enter will emit. (It is right)

However, turn B' monitorable(true -> false -> true), A' area_enter wouldn't emit. ( I think it should emit)

Additionally, every change on B's monitoring (true -> false or false -> true) will makes A' area_enter emit. ( I think it shouldn't emit according to the principle)

I hope that a appropriate change will happen on there and make them liked described.

Steps to reproduce

1. open the function "display collision area"
2. press "D" until the small area overlap with the big .
3. change B'monitoring and monitorable,then oberve
