Result fail to track buff "Stampede" of PackLeader

[SANA4149]

Describe the bug

For Packleader hero talent, there's a hidden buff Stampede that shows when 4pc effects begin and finish. It's the most intuitive parameter to evaluate the efficiency, two or one Stampede in one Lead From the Front is totally different. The abilitiy section can only show the detail as dot-like.

Expected behavior

There should be a stat of Stampede(spell ID:1250068) in buff section, just like other buffs.

To Reproduce

Just simulated any Packleader hunter with S3 4pc.
