Binary editor can't be opened in more than one split

1. Open a file in Creator's binary editor.
2. Split the editor.
   The editor will be split but one of the splits will be empty.
3. Try to open the same file in the other split, too.
   You can open the file in this split, but it will be closed in the other split. It's the same with the image viewer.

It would be nice if Creator could use splits for binary editors, just like it can for text files.
