[Gameplay] Anivia passive doesn't trigger if killed by Razorfins

In a game of Black Market Brawlers as Anivia, my passive was definitely available, and after escaping from the enemy Yi I was chased down by a group of Razorfins, who attacked me and killed me, leaving my egg available and unused.

Full set of my unresolved bug report threads:

• Match History still calls north team "Purple"
• Team Builder lobby doesn't dissolve if an invited player disconnects
• Zyra passive can't be fired with an unranked ability's key
• Ahri R should start cooldown upon death
• Targeted abilities sometimes fizzle if their target moves away
• Storm Shield relics on Crystal Scar can be displaced
• Orianna's Ball may return while distance indicator is still yellow
• "Enable HUD animations" does nothing; "Disable minimap movement" ignores some input
• Galio W doesn't provoke heal from Twitch passive
• Teemo passive prevents capture of a neutral Twisted Treeline altar
• Anivia passive doesn't trigger if killed by Razorfins
• Vilemaw death timer not appearing
• Item Set construction doesn't properly label items' map availability
• Removed items are still displayed in Item Sets
• Zyra passive on quick cast is erratic
• Zyra can use trinket while in passive
• Inactive Heimerdinger turrets not damaged by Rift Herald

I will be bumping these threads periodically, though in a way that avoids flooding.
