[Gameplay] Yi Alphastrike and Sivir Spellsheild

Issue: When Yi Activates Alphastrike on Sivir while her activated spellsheild is up, the spellsheild will pop and show the proper animation for doing so, but the strike itself will still do damage.

1. Yi Activates Alpha strike
2. Sivir activates her spellsheild in response - usually during the dashing aspect of Alpha strike.
3. Sivir's spellsheild is proc'ed providing mana
4. Alphastrike has its short delay prior to Yi reappearing on the field and damage being done, then the damage is inflicted regardless of the spellsheild.

I have had difficulty reproducing this bug however in a custom game at level 1 with no items. The player playing YI at the time of the issue acknowledged it and was equipped with:

Last Whisper Blade of the Ruined King Beserkers Greaves - Homeguard Skirmishers Blade - Warrior Phantom Dancer Infinity Edge

And Had Oracle Lens as his trinket.

It is difficult to say if a higher level, or any of these items inparticular could have caused the issue - There was noone else alive at the time the bug occurred in game.
