Arduino node, not automatically reconnected after unplugging

Which node are you reporting an issue on?

• Arduino-board ( hidden node )
• Arduino in

What are the steps to reproduce?

Start with Arduino Uno with StandardFirmata 2.5.8 connected.
Unplug and Plug back in. ( the delay before being plugged back in doesn't seem to change the issue )

What happens?

• the status light remains connected.
• The arduino-board node writes "Arduino serial port closed" to debug console.
• Although the device is plugged back in, the node remains inactive, no more messages arrive from it.

What do you expect to happen?

Firstly the status should change to disconnected when unplugged.

Having looked in the code it seems an auto reconnect routine exists, with an interval of 5 seconds. So I would expect the ardunio-board node to reconnect, and the arduino-in to start receiving messages again.

Please tell us about your environment:

• Node-RED version: 1.0.0
• node.js version: 10.16.3
• npm version: 6.11.3
• Platform/OS: Windows 10
• Browser: Electron ( running as app based on this repo https://github.com/dceejay/node-red-project-starter )

Reproduce with an Arduino Uno running StandardFirmata 2.5.8, then inspect the Arduino-board hidden node and Arduino in node, including the existing five-second reconnect routine. Done means unplugging changes the status to disconnected and plugging the device back in restores Arduino in messages.
