Best practice is to mount wheels with bike on the floor, so gravity ensures they're fully seated to the tops of the dropouts. Or, mount them on the stand, but move to floor and open and retighten QRs before any brake adjustments.
That is what I always do. I can get the wheels onto the bike in the repair stand, but I then put it on the floor and make sure that the wheel is fully seated in the dropouts. Particularly important with conventional quick release wheels and disc brakes
