Ward Debris Spawn Momentarily Counts as Object

Not sure if anyone has noticed this yet, but the spawning of ward debris (very momentarily) counts as an object, similar to a minion. I've seen two instances of this now, first when I was playing Lee Sin and attempted to Q onto someone destroying a ward. My Q actually marked the ward debris for about half a second and gave "invulnerable" text or something of the sort. The second time I saw this was when a ward decayed while a Teemo shroom was on top of it. When the ward debris spawned it detonated the shroom.
