Zyra seed.

Not sure if this is a bug or not but seems strange, just had a game as Bard, when I was up against a Zyra supp. She had a miss fortune that was positioned behind one of the plants, so I throwed out my q to stun her and the plant. It was only the problem that a seed was before MF, and the q instead locked on to the seed and plant. Didn´t think that the seed would count as an object or a wall, but the seem to. Should the q of bard react to the seed of zyra is my question, and does it work the other way with seed and then an object?
