"Next (bow) attack" buffs do not apply to Fussilade triggers from channeled Flurry

Now, I am not entirely sure if this is a bug or intended, but figured I’d report.
As far as I know, when used with channeled abilities, buffs that apply to the next attack apply to the entire channel.
However, if I am using channeled Flurry with Fussilade, those buffs do not apply to the multishots that are part of the channeled ability, making them rather pointless for such a build.

I’d expect that to be working as intended, since Multishot has it’s own skill tree & you can put it on your bar, therefore it won’t inherit any modifiers from Flurry.
