Sivir's spellshield vs Vayne's silverbolts / condem [GAMEPLAY]

Usually Sivir can't block the 3rd Stack of Vayne's silverbolts with her spellshield, but if Vayne tries to apply the 3rd stack by using condemn Sivir can block condemn with her shield. In this case not only the "push away effect" of condemn is blocked, but also the stacks disappear from Sivir without dealing bonus damage.

How to recreate:

1. Let Vayne autoattack Sivir twice, to apply 2 silverboltstacks.
2. Let Vayne use condemn on SIvir, which she blocks with her spellshield.
3. See that the silverboltstacks disappear without triggering the bonus damage, even though it's usually not possible to block the 3rd stack with spellshield.
