Apollo - Flawless Advance not refreshing duration near tail end

[HexSine]

This could be intentional but feels like a bug. Each time flawless advance is used the duration is refreshed. If Flawless advance is used near the tail end of the duration however, it casts appropriately, but does not refresh the duration.

Here's a video for demonstration purposes.
Is this intended as a Bug or a Feature, it seems weird that the bar would remain on screen for it.

If we could get clarification on this, that would be fantastic, thank you!

Here to say I've got this issue too. I think it has something to do with it being CAST during the recast window, but because of the charge, the actual attack/spell going off after the recast window is already finished. At least, that's my best guess.
