I haven't seen this posted before, and while this is a minor thing, it negates the benefit of the mounts. I have the Mammouth Mini pet, which as people know, gives +2% outgoing health boost. When you enter a Sigil, that boost is removed. Since that is where the mount boosts would make the most sense, either this is a bug, or, it is working as intended, and it needs to be changed so that whatever mount you had at the sigil, its benefits transfer into the sigil/dungeon fight.

I don't think mount stats have ever worked in dungeons at all, so yeah it is either overlooked or working as intended either way the stats for mounts are useless in their current stat.
