The crafting/salvaging stations had this same issue a while ago; when a habitat is unpowered and thus the research station is unusable, it still displays the "Left click to interact" hint text, except nothing happens when clicking the interaction node (correctly, since there's no power), which can be confusing. Same solution as with the other stations, the hint text should change to "no power" when the hab is not powered.
(I was kind of sure this issue will resurface with the new work station, by the way. ;)
