Thank you so much, that was fast. I looked at Rect2 and it seems like it's also missing the change from #32478. Do you think you could include it in the fix?

godot/modules/mono/glue/GodotSharp/GodotSharp/Core/Rect2.cs

Lines 123 to 128 in 7a90c56

	public readonly bool Encloses(Rect2 b)
	{
	return b._position.X >= _position.X && b._position.Y >= _position.Y &&
	b._position.X + b._size.X < _position.X + _size.X &&
	b._position.Y + b._size.Y < _position.Y + _size.Y;
	}

Good point, will do in a bit, away from the computer for now, can do it in a separate one too, will check Rect2I as well
