研究方向
Look into the tab thumbnail management logic, likely in the TabTray view controller or the Homepage view. Check how thumbnails are captured and displayed when switching between tabs. The bug suggests a cache inconsistency where the last visited tab's thumbnail overrides the homepage thumbnail. Focus on the thumbnail caching mechanism and the transition between tab tray and homepage.
