Does the CircuitLab simulation ignore OpAmp power rail current?
I think CircuitLab doesn't simulate the power draw by the opamp (neither for the output, nor for the quiescent current needed by the IC innards).

The reason for this, I guess, is that LM324 is a jellybean part, made by a handful of manufacturers, so if you truly want to simulate, you would need to specify exact part number and manufacturer, not just "LM324".
If you go that direction, then it's probably best to use the manufacturer's SPICE models for that opamp, even though I'm not sure if they simulate the quiescent current as well, but it's more likely that they do.

E.g. I just tried similar to your schematic in LTspice and it seems they simulate the power rails, I was able to measure the current going in the opamp.
