Pulseaudio shows Line Out (unplugged) when headphones are plugged in.

I am filing this bug upstream as requested from https://bugzilla.suse.com/show_bug.cgi?id=950204
My desktop has headphone and microphone jacks on the side panel, and an array of audio jacks on the back panel. In this case, I have two audio out cables plugged into them, one from the back panel (called Line Out in pavucontrol) and one from the side panel (called Headphones in pavucontrol).
To enable toggling in between the audio sources, I disabled auto-mute in alsamixer within the terminal.
This means I am able to select whether to use my speaker or my headphones as the primary audio output.
However, when the side panel jack is used, pavucontrol shows "Line Out (unplugged)" and "Headphones (plugged in)" despite both devices being plugged in at the same time. The strange thing is, I am still able to toggle in between the two different audio outputs without issue.
