[Gameplay] Bard's W is used on allies taking lethal damage but not saving them when it should

In this clip, Riven's auto attack does 109 damage.

Bard's shrine heals for 65.

Bard's health at time of death is 77.

If Bard casts his W on himself, he should be able to sustain one auto attack from riven. In this case, we did both at once- Riven auto attacked right as bard self casted his shrine. What resulted was Bard using his shrine just before dying, receiving the healing postmortem but not rising up like a Bard Jesus, and the W was put on cooldown. The shrine is consumed, Bard is dead and frustration is had. To reproduce, follow these steps:

1.) Bard or an ally needs to get to low health. 2.) Bard casts W on himself or ally as they take lethal damage (same tick). 3.) The Bard W is consumed whether or not it will save them from lethal damage and the champ taking lethal damage dies whether or not the shrine should have been enough to save them.
