Now I have to wonder if my browser is broken; I even did a search on the page to make sure....

In any case, the description confirms my suspicion: you do not want to use that here. The purpose of that action is to allow you to more easily run as a scratchpad something that requires a terminal --- not to use the terminal itself as a scratchpad. Use the normal scratchpadSpawnAction for that. In fact, you might want to use scratchpadSpawnActionTerminal for the other actions instead of this one.
