I encountered a bug when using the setGraphContainer method. The source code is marked with the need to fix ME! I saw that the init method in Graphjs is replaced by the constructor of class Graph, so setGrapContainer will report an error when it executes this.graph.init (). When I initialize an instance of the Editor class, I call the Graph constructor, but I can't pass the container parameter in smoothly, and setGraphContainer has a bug that causes some trouble.
