[GAMEPLAY LoL Base Game] Qiyana Q projectile 'Fizzling'/inconsistant

There is a bug where Enemies will not be hit by the latter portion of the Empowered Q. You can recreate this by Lining up 2+ Enemies, aiming the end of the first part of empowered Q just before the second Enemy, and the 2nd potion of the Q will fizzle into nothing, doing no damage to subsequent enemies in the line of fire. Attached will be a video showing this several times. Black cleaver stacks are used to confirm it is not a visual bug as the stacks do not apply.

My understanding is that the second part of the Q code is either not being triggered because:

it cannot start the new projectile so soon after an entity is struck, or the second part of the Q cannot create the projectile while inside an entity.
