Apollo's Flawless Advance charge window cancels Binding Word's immobilization effect.

[Designated Redshirt]

Bug:
Apollo's Flawless advance has a charge up time.
Warden drops a Binding Word on him.
Apollo fails to move far enough to prevent the immobilization effect from going off.
The audio cue for Binding Word's immobilization effect plays and the immobilized effect should be applied.
However, if Apollo is currently in the charge-up window for Flawless Advance when Binding Word's immobilize effect would be applied the Flawless Advance's thrust triggers and cancels out the root entirely. It doesn't just move him a bit and then leave him immobilized at the spot his Flawless Advance ended, it entirely prevents the immobilize effect from being applied; wholly cancelling it.

Expected behavior:
Flawless Advance should be treated as a movement ability. Binding Word's immobilization audio cue plays and the effect is applied to Apollo. If Flawless Advance is currently activated and in its charge-up window when Binding Word's immobilization audio cue plays then Flawless Advance gets cancelled and Apollo is immobilized.

On further inspection of a couple examples in replays I have determined I am wrong and that the effect is just a result of Riposte being used a split second before Binding Word completes.
