[Gameplay] Thresh Lantern (Dark Passage) can't be clicked on

Thresh Lantern cannot be clicked on while self-cc'd.

This primarily applies to Blitzcrank hook (Rocket Grab) which applies a self-snare during the cast time. It also affects Nautilus Anchor (Dredge Line), and should also apply to Jinx laser (Zap), Jhin laser (Deadly Flourish), among others.

The primary impact of this is that is disables the 'Threshcrank' interaction of artifically extending the distance of blitzcrank hook (the pull distance is further, but the projectile travels the same distance)

This bug was previously introduced in patch 4.03, acknowledged by Riot CertainlyT shortly after, and a fix was deployed in patch 4.5

The Threshcrank combo worked fine as far as patch 7.08, and it seems like it broke again in patch 7.09 with the introduction of the Dark Star Thresh 3v3 game mode.

Ever since I noticed that it didn't work, I've been keeping a log of every patch to verify that its still non-functional

To Reproduce this Bug

1. Have Blitzcrank and Thresh on the same team, and in range of each other
2. Toss a Thresh lantern, preferably a moderate distance away from Thresh
3. Have Blitzcrank stand within activate range of Thresh lantern
4. Activate Bltizcrank hook, and attempt to click on Thresh lantern while the hook projectile is traveling. Spam clicking will illustrate the problem better.
5. Blitzcrank will not grab the lantern until his casting animation is over, despite not being affected by any enemy CC

This can be reproduced 10/10 times
