Confusion around new stat "Arrow speed"

As a ranger I took the node "Feathered fletching" which makes increases and decreases to projectile speed count towards projectile damage. There's a quiver base type called "Volant quiver" which grants arrow speed, however this stat is not underlined so no additional information is related to this stat.

Does increased arrow speed count towards increased projectile speed, or is it unrelated?

Update:

While I can't be 100% sure, the projectile speed modifier on my poisonburst arrow does not change in it's damage breakdown menu when swapping to the Volant quiver, so I'm assuming that arrow speed does not relate to projectile speed. If someone could give me a definitive answer that'd be really appreciated, but for now I'm going to assume arrow speed does not work with "Feathered fletching".

Bump

might be a bug or artifact of a prior build. It might have been arrow speed in a previous build but got changed to projectile speed to be more inclusive of all projectiles. You might want to post this in the bug forum instead if you cant observe any effects.
