[GAMEPLAY] Zhonya's Hourglass Active Penetrated by Enemy Fountain

In my last Morgana ranked game, as I was making a touchdown in the enemy's fountain and about to win the game, I witnessed the laser of the enemy's spawn fountain hitting me despite me being in Zhonya's Hourglass active. Here's how:

.

1. Outside enemy fountain, I auto-ed enemy Braum who was in his fountain.
2. I walked in fountain and got shot by fountain lasers (Braum was attacking me).
3. I ulted (not sure if I auto-ed Braum before ulting).
4. I hourglassed with just enough spare health before fountain finishes me off with its laser (not sure if I auto-ed Braum before hourglass-ing).
5. I saw myself turn to gold and I heard the hourglass active sound effect for a split second (maybe 1/5 of a second).
6. I get damaged from the laser of the enemy's fountain in my hourglass's gold state.
7. I died, and I wasn't gold anymore when I died (then I yelled "hackr" in /allchat).
8. About 2 seconds later, the enemy Nexus exploded and my team and I won.

.

Unfortunately I was not recording or screenshooting. My Morgana ranked game occurred on 4/5/2017, ending around 10:50 pm in Pacific Time.

Although I never witnessed this behavior from the fountain before this Morgana game, I had witnessed similar behavior when the fountain laser is rekting people to death despite the people being "invulnerable" AFTER having the enemy Nexus destroyed. This similar bug happened many times. I don't have any media reference to this similar bug either.

I think the two bugs are connected somehow. Also watch this funny Solwolf video, the part when Teemo dies after having the enemy Nexus destroyed at 40:30 by Jinx. This Teemo death is old, maybe not connected, but it is a similar bug to the mentioned similar bug above, and you gotta watch it. https://youtu.be/S5FLgx4JaDI?t=40m30s
