Creeps on zipline don't lose hp for damage that knocks them down

[short-lived]

Prior to the 09/12 update, when you hit creeps on a zipline, they would take the damage and fall with adequately reduced hp.

Now, when you hit them, they fall with full hp no matter how much damage they took. Pretty significant hit to Talon's waveclear.

I don't know if it's a bug, but it's an undocumented change.
