no cover art on video in explorer and no bitrate in MediaInfo if you stitch chapters through chapter editor.

I found an interesting bug, if you take the xml file of chapters and paste it through the chapter editor into a video that has no chapters, the video preview in explorer disappears. Also the display of aac audio and video bitrate in MediaInfo disappears, it shows up when you save a chapter to mkv external. also an interesting feature, if there are already chapters in the video and save another xml chapter into it using the same method, this bug does not appear.
