Start by reproducing the issue in the demo-general entry point at https://lowcode-engine.cn/demo/demo-general/index.html using the listed engine, extension, demo, and Chrome versions. Inspect the container column layout and chart rendering behavior after dragging a chart into a split container. Done means charts retain a fixed usable size instead of continuously expanding.
