研究方向
Investigate the selection handling and keyboard event listeners in the bpmn js source code. The error 'A DOM element reference is required' suggests that during deletion after shift+click selection, a DOM element reference is missing. Look into the BoxSelection behavior and the delete key handler. Check if the selected elements are properly referenced when deletion is triggered. Relevant files might include selection/Selection.js, features/box selection/, and keyboard/KeyboardBindings.js.
