[Bug] Viscous' Puddle Punch (T3) triggers Melee Charge/Crushing Fists cooldowns but deals no bonus damage

[ljx111111]

Hi, I found a potential bug while playing Viscous.

After upgrading Puddle Punch to Tier 3, if I buy Melee Charge or Crushing Fists, using Puddle Punch will put these items on cooldown. However, the ability does not deal any extra damage from these items. It seems like the proc is consumed but the effect isn't applied.

I have verified this behavior in both Sandbox mode and Custom matches. Is this intended behavior or a bug?
