Auras supported by March of the Legion still count as a "persistent buff" for UI

As shown in the image above, all the auras on my visible hotkeys are supported by March of the Legion's Blessing Support and I have the UI option "Show Aura Icons" turned off. These auras do not show up on the buffs section of my UI despite having a duration and no longer being permanent.

This is not consistent with existing temporary buffs that are also counted as auras, such as Smite's buff (which still shows up on the buffs section of my UI even when "Show Aura Icons" is turned off, as it is not a persistent buff).
