Fuel flow increases with starter engaged

Is this a limitation of X-plane?  What I'm seeing is that the fuel flow (FF) increases as soon as you engage the starter.  When I hit the starter FF goes up to like 50gph, but as soon as I introduce fuel it jumps back down.

Really, FF should show no indication until you move the lever out of cutoff.  Once you do so, you should see fuel flow register immediately, even before you see the ITT rise.  Many pilots are taught to check that indication as part of the start flow.  Source:  me, former corporate pilot IRL.

When watching the video produced by Daher showing a detail of the engine start procedure, you can see on the Fuel Quantity/GPH gauge that there is a positive value for fuel flow immediately upon engaging the engine starter.

Specifically... watch from 2:13.  The Fuel Flow readout is on the far left side of the MFD in the second box up from the bottom.
