Binary input does not use external state for switch in knx

# Problem

I have the Panasonic KNX Gateway INKNXPAN001I000 with 4 Binary inputs. These can be configured as a switch input. I like to use it for my light bulb to turn on and off. Now i have also a visualisation and if i change the light state there, the switch needs to be pressed two times to change the state of the light again.

# Reproduce

- Parametrise the Input to be a switch
- Set to toggle on rising edge
- Create a Group address for `Turn On/Off light` and `Response Turn On/Off light`
- Add the communication opject to the `Turn On/Off light` group and as second to the `Response Turn On/Off light`
- Add the `S-Flag` to the communication opject.
- Now pressing the switch will toggle on/off
- Send `On` to the `Turn On/Off light` group address via ETS (while the last state was `Off`)
- Monitor the Bus and reid the state of `Turn On/Off light` (it will turn back the state `On`)
- Now press the button and it will send the state `On` to the bus and not `Off` like expected!
I've tried to add the Response address to the switch and add the S-Flag to it. If i change the state manually over the ETS, a read will show the correct state but if i press

# Wanted

If the light was turned `On` or `Off` by using not the Binary Input, the Input should get the current state back from the bus and knows what to toggle if the button will be pressed the next time.
