Root cause: every local resource preview tab kept its own /api/local-folder/events EventSource alive. Hidden PDF and Office tabs consumed browser same-origin connection slots, so later preview iframes/file reads stalled and rendered as blank pages. Changes: - keep passive resource file watching active-tab only - close inactive resource-tab EventSources on tab activation and release - update the bug record with the PDF fifth-open and XLSX fourth-open repro and verification Verification: - node --check rust/crates/mnote-web/browser/document-resource-tab-runtime.js - cargo test -p mnote-web --manifest-path rust/Cargo.toml pdf_preview_page_does_not_render_visible_toolbar - cargo test -p mnote-web --manifest-path rust/Cargo.toml document_shell_returns_page_aggregate_snapshot - cargo build -p mnote-web --manifest-path rust/Cargo.toml - browser smoke: opened 5 XLSX previews; #4 and #5 completed with tableCount=1 - browser smoke: opened 5 DHA PDFs; #5 rendered 8/8 canvases, iframeCount=0, browser errors=0

更新时间:2026-05-12
状态口径以当前仓库真实代码与真实验证结果为准:
[done]:问题已修复,且已通过代码、smoke、浏览器或截图证据验证[process]:问题已确认存在,仍在修复、验证或等待收口
分类方式
bugs/默认镜像design/的主线分类方式。- 当前主线缺陷按对应大类放置,例如:
01-tree-first-graph-kernel/02-convex-rust-long-term-architecture/03-rust-web/04-tree-domain/05-editor-mainline/06-mindmap/07-ai/
- 每个大类继续按
process/与done/分层。
归类原则
- 缺陷归类以真正 owner 和长期主线为准,不以表面症状命名。
sidebar、topbar、breadcrumb、文档页壳、Wolai 体验对齐、页面树与主编辑器整体体验问题,优先归到05-editor-mainline/。projection、row model、selection/focus model、keyboard、DnD、tree command、page_tree/file_tree/sidebar_tree协议问题,优先归到04-tree-domain/。transport、route、SSR page shell owner、compat/bridge 边界问题,按 owner 判断是否落到03-rust-web/或05-editor-mainline/。
流转规则
- 新确认的缺陷先进入对应大类的
process/。 - 缺陷在真实代码中修复并完成对应验证后,必须移动到对应大类的
done/。 - 不允许在
process/与done/同时保留同一条缺陷。 - 若后续发现旧缺陷记录归类错误,应直接迁移到正确大类,而不是在错误大类继续追加。
