Worked on the AlistGo/alist-web project to improve video playback reliability by addressing a bug affecting the auto_fullscreen feature. Focused on frontend development using JavaScript and TypeScript, the work involved refining switch-case logic in key video components to ensure correct handling of URL parameters. By adding missing break statements in aliyun_video.tsx and video.tsx, the fix enabled auto_fullscreen to respond accurately to searchParams, directly resolving issue #283. This targeted patch enhanced the user experience by making fullscreen toggling more predictable and reduced potential support requests related to playback behavior, demonstrating careful attention to detail in frontend bug resolution.
