Research direction
Investigate the connect tool's drag behavior and label highlighting. Check relevant source files, such as 'ConnectPreview' or 'LabelSupport' modules, in the bpmn js repository. Reproduce the bug locally and identify the CSS or event handler causing the unwanted label highlight during drag on empty canvas.
