Is Jitsi Thumbnails are not Dynamic?

I am creating a custom view.

where a participant is pinned I am showing it left side as a large Thumbnail..
remaining remote participants as small on the right side.

whenever I pinned the thumbnail of the remote participant from the right side.
left side large Thumbnail is not updating,

updating the key of pinned participant still not updating it’s showing up the local participant always

{this.props._participant.length > 0
      && this.props._participant.map(_participant => _participant.pinned
          && (<Thumbnail
              horizontalOffset = { _horizontalOffset }
              key = { `remote_${_participant.id}` }
              participantID = { _participant.id }/>))}
