[Bug] Husbandry talent buffs player-bound instead of mount-bound

I leveled up one of my characters into the Husbandry tree. I got about all talents there. So I tamed some animals in my Open World; this Open World already had some tamed animals tamed by another character without any talents in the Husbandry tree. Now when I look with my Husbandry character, all mounts have the buffed speed (no matter who tamed them); when I look with my Miner characters, no mounts have the buffed speed (not even the ones tamed by my Husbandry character). I double checked this with another player present: When logged in with my Husbandry character, all mounts have the buffed speed (no matter who tamed them); when I logged in with my Miner character, no mounts have the buffed speed (not even the ones tamed by my Husbandry character). I would have expected these buffs (more speed, more stamina, less food / water consumption) to stick with the mount, not with the character...
