It's just my guess, since it seems that specific quest might be responsible for holograms disappearance. I did some research and it seems Panam's quest "Lighting breaks" triggers it, in this case it would totally make sense if it disappears intentionally. You overheat the terminals in power plant station after all. Game doesn't tell you a lot of things anyways, so I wouldn't be sure that it's clearly a bug.
Interesting. Need to see if the holographic displays shuts down after triggering the EMP.
