How to render participant with "restoring" connectionStatus

Dear all,
Sometimes I faced to a situation in which one participant occurs twice in the participants’array with restoring connectionStatus as in the attached image (the participant having the “name” equal to “HV - Thien Quan - 7082”).
I wonder why such situation happens. And when it happens, which participant I should make visible. It happened that such participant has 4-5 cameras (all in black) because by default all participants are visible.
I do remember that with the interrupted connectionStatus, I have the same issue.
Many thank in advance for your help
