Fatal Flourish doesn't repeat with channeled skills

As per title, using fatal flourish with a channeled attack skill doesn't repeat the attack.

While one could think this as obvious, the tooltip for the channeled attack still CLAIMS that the "attack repeats 1 additional times".

Tested this with Blade flurry, Scourge arrow and Snipe (from Assailum) with identical results.

This is just tooltip issue.
Autogenerated data tooltip in this game in general is pointless mess, deal with it.

I assume you expecting to reduce your BF mana consumption per sec in half by using Fatal Flourish. This could work if each repeated "action" while channeling BF would be considered as a separate attack. But it's not, the whole channeling process from pressing the button down to releasing the button is the attack. Obviously Fatal Flourish is not meant to repeat a channeling attack.
