Widow’s Insight Bug

Hello guys! Out of pure curiosity.. I recently came across (again) with a weird bug in arena whenever I face as first or second Black Widow (Deadly Origins) , the next champions I face, all get periodically during the fight, the Widow’s Insight icon! And this time I used Black Widow myself as the first champion and the next one got the icon too! I don’t believe it’s a synergy I miss somehow, so it has to be a visual bug in my opinion. I think I started seeing this bug since the end of November pop up in arena. Did anyone else came across with this weird interaction of Black Widow? If somehow it is a synergy, then I guess I’m dumb 😂😂
