研究方向
Investigate the webview lifecycle in Theia, focusing on the behavior when the window is maximized or minimized. Check the source files related to webview handling in the @theia/core package, and reproduce the issue using the provided sample. Look for any event listeners that might cause an unintended refresh, and consider if there are differences compared to VS Code's webview implementation.
