[GAMEPLAY] Nocturne's Spell Shield not blocking Dragon's Knockback on Liftoff

I don't know if this is true for other spell shields, such as Sivir's and Banshee's Veil. However, I know Morgana's Black Shield will prevent the displacement.

I am not sure if that's intended, but it seems like it shouldn't be happening.

To recreate:

1. As Nocturne, get into the Dragon Pit (make sure you're in range to be knocked back).
2. Cast Q or E, then cast W as the Dragon begins to come upward.
3. The W shield will not be consumed and Nocturne will still be knocked back.
