Emoji in ZMSDKThumbnailVideoItemView is not displayed fully and emoji freezes in the container

Hi @jon.zoom thank you for the information, I have tested in v5.9.3. the freeze issue is solved but the emoji cut is still there in the size

let thumbnailVideoView = ZMSDKThumbnailVideoItemView(frame: NSRect(x: 0, y: 0, width: 245, height: 140), userID: userID as! UInt)

But the emoji cut is not happening in the size

let thumbnailVideoView = ZMSDKThumbnailVideoItemView(frame: NSRect(x: 0, y: 0, width: 350, height: 200), userID: userID as! UInt)

screenshot attached for both the size
