Arduino IDE not showing attached board comm port in "Tools>Port:" drop down menu. However, the port is recognized and displayed correctly in the lower right corner of the IDE screen. Please see attached file.

Contributor guide
Research direction
Start by reproducing the issue in Arduino IDE 1.x with an attached board, comparing the Tools>Port dropdown with the port shown in the lower-right status area. Use the attached screenshot as the expected symptom; done means the recognized board port appears in the Tools>Port list and can be selected.
