As demonstrated, the necromancer pet stops attacking after being stunned. He can only be compelled to attack again if you change his stance during combat (i.e., from passive to defensive or aggressive.) I can duplicate this behavior on an elementalist pet as well. It happens absolutely consistently after the pet is stunned.
UPDATE: A "purple-name" moderator/community team member acknowledged shortly after I posted this video that the developers have duplicated the problem and it's in the tracker to be fixed. No ETA on when this will occur. Stay tuned...

I have seen this before on my pet. I thought I was the only one it happened to. You are correct it is fixed by changing the stance.

@Ashur420 It's apparently affecting other pet classes as well, not just necros and ellies. I've had confirmation by at least two rangers that it happens to them as well. Working on finding out if it impacts beastmasters and druids also.
