video's of tiktok stopped video playback when its Tab is hidden. It seems to be related. When window is occluded, front Tab is set as hidden Tab. PiP video's document visibility still belongs to original Tab. When PiP video becomes fullscreen, the original Tab is set as hidden Tab by window occlusion.
