[GAMEPLAY] Possible Katarina/Zhonya's Hourglass bug

(Patch 5.2, date 2/1/2015) - I recently played an ARAM match, and the teams resulted in one player as Katarina on the enemy team, and myself as Soraka. The match went on as one would expect, and half-way through the game, Katarina somehow managed to escape my [E] - Equinox with her Shunpo after leaving Zhonya's Hourglass stasis. This presents some issues that can result in illegitimate victories on Katarina's side, and on addressing it the opposing Katarina and I agreed to report this possible bug.

Possible steps to replicate the bug(?):

• Have Katarina and Soraka, both on opposing teams to each other.
• Have Katarina purchase Zhonya's Hourglass, then in combat with Soraka, use its active ability.
• Have Soraka cast [E] - Equinox on Katarina while she remains in Zhonya's Stasis
• Have Katarina cast [E] - Shunpo after leaving Zhonya's Stasis

While I sadly don't have video or screenshots to back this up, this should nevertheless be investigated due to the problems a Silence-ignorant AP Assassin could cause in later matches.
