[Gameplay] Illaoi's W occasionally fails to cast against certain enemies

The bug appears to have been introduced around the same time that Illaoi's W was changed to no longer fizzle if you were stunned mid-dash.

Attempting to cast W on tiny Krugs causes Illaoi to leap at her target, be caught mid-air, and then slowly return to an idle position before attempting to cast W again. It can be crippling, as it's effectively applying hard crowd control to yourself while you wait for the animation to end, and it can be difficult to cancel the W command (especially with auto-attack turned on).

To replicate:

1. Kill an Ancient Krug to break it into its components.
2. Kill the medium sized Krugs to produce tiny Krugs.
3. Cast W at a tiny Krug.
4. Pretend you're in the Matrix.

It doesn't work 100% of the time, and the distance between Illaoi and the krugs appears to influence the bug. I haven't encountered this issue on other enemies, but other small targets like Zz'rot creeps and Heimer turrets may produce similar results.
