Neeko's Health Bar Bug

I was playing a game with Neeko on the other team, a ranked game if that matters. Towards the last few minutes of the game, I was stuck seeing Neeko's health bar at 121 HP. Even if I or my teammate damaged Neeko, I would still see Neeko's health at 121 HP. Sadly, I couldn't get a screen shot of the bug since I mistaken what key it was to take a screenshot.

Edit: I have no clue how to recreate this, but if anyone knows how to, post it in the discussion, please!
