[GAMEPLAY] Elder Dragon Execute Threshold Indicator Persists After Buff Has Expired

In one of my recent games, I flashed then autoed to kill a Yasuo that had an Elder buff execute indicator on his health bar. The auto connected and brought him below execute threshold, but failed to kill. Some time later as my team was ending the game, he and a few of his other teammates ran out of their nexus still with Elder buff indicators on their health bars after being damaged. I even brought Yasuo below threshold again, but the Elder buff didn't proc and I had to auto again to kill him. I checked the replays, and the Elder buff had expired in the middle of a teamfight some time before I flashed. Somehow the little white bars popped up on his team's health bars even after Elder buff expired.

There isn't a way to prove I saw the Elder indicator after the buff expired, because the replay doesn't show the Elder buff execute indicator. But I know both players on my team and the enemy team saw Yasuo "survive" Elder buff the first time, because it was brought up in chat during and after the game.

I don't know if it's reproducible either, but to summarize some key points:

• The Elder buff expired in the middle of a teamfight
• The indicators persisted after the buff expired
• Both players on my team and the enemy team noticed this
• My team also had Infernal soul at the time

This is my first post, so please tell me if I missed something.
