Tiktok glitch that plays audio of another video into the one you're watching

Alright gng I think it's only me but, there has been this annoying bug that keeps playing audio of another video whenever I'm watching a seperate video. Like when I'm watching a random rant video it's either gonna loop the audio while the video has not yet finished, or play another video'​s audio. And both will continue to happen even if the video is paused. Unfortunately I don't have a footage of this bug:/​
