Home Assistant nodered: Open dashboard button in nodered uses wrong port

### Current Behavior

I constantly got error 404 when trying to open up the new 2.0 dashboard using the button in the top right corner of the Nodered window.

I use the Nodered plugin/app for Home Assistant.

On closer inspection of the actual link it was trying to open, I saw that it used port 8123 instead of 1880, where the dashboard is hosted.

I have not found a way to replace the 8123 (HA) port to 1880 in that link. I also don't know if it is a bug or simply my setup that behaves wrongly. Just wanted to let you guys know.

Cheers!
