Relay "Closes" even though no current can flow through coil

Apologies if this is a duplicate, I could not find any way to actually search the forums themselves, only the main CircuitLab website.

I have this circuit:

I'm trying to build a schematic for a real world circuit for a motorhome, but I noticed that the relay doesn't seem to work correctly, so I modified the circuit to illustrate the issue as clearly as possible. If you run a simulation you'll get alternating current through the light bulb which shouldn't be possible: As no current can possibly flow through the relay's coil there should be no way it could close and activate power to the light bulb.

Unless I'm missing something? This seems like a really basic principle to have not working properly.
