Using pins D9 & D10 on the MDBT42Q

I just tested with device I just have here - nrf52840 dongle and indeed have some issues with this if I connect over bluetooth. However when I connect over USB serial it worked. Can you try over serial console without using bluetooth console at all?
this was over serial

>var d=0
=0
> NRF.disconnect();NRF.restart(function(){­d=1;})
>d
=1

when tried bluetooth

>var d=0
=0
Disconnected from Web Bluetooth, Dongle c56e
>NRF.disconnect();NRF.restart(function()­{d=1;})
Found NRF52840Dongle, 2v08.156
>
Connected to Dongle c56e
>d
=0

I also tried without NRF.Disconnect - you need to disconenct after calling it, it prints

>NRF.restart(function(){d=1;})
BLE Connected, queueing BLE restart for later
=undefined

and should restart later but d is still 0 after reconnecting.
Strange, this worked previously. Not 100%, sometimes I saw this too, but mostly it worked fine. If this happened previously, after E.reboot() it worked.
