fix(panel): 记忆入口落在「更多」行之前，不再被展开的菜单盖住（#573） by modusensus · Pull Request #576 · slow-stack/mneme

现象（issue #573）

宽态侧栏里，记忆入口排在「更多」这一行下面；点开「更多」时，弹出的菜单正好压在这一行上把它盖住。

根因不是「落位算错了」，而是宿主 0.2.2 把 PanelMoreMenu 也追加进了同一个 nav.panelList：v0.8.x 时 portal 到组尾刚好是面板组尾部，现在组尾变成了「更多」。place() 仍然 appendChild 到末尾，于是入口落到「更多」之后。

改动

文件	改了什么
`dsh-mneme/lib/client.js`	`place()` 的宽态分支先找 `[class*="moreAnchor"]`：命中就 `insertBefore(created, more)`，没命中（老宿主没有这一行）原样退回 `appendChild`。新增 `findMoreAnchor` 一行 helper。
`dsh-mneme/lib/client.js`	幂等判据改成 `created.nextElementSibling === more`——稳态下不能写 DOM，否则 `insertBefore` 会自激成 mutation 风暴（这个坑在 `place()` 上方注释里记着）。
`dsh-mneme/lib/client.js`	头注释把「于是它是该组的第三行」改成「该组的一行」，并写明落点是「更多」之前以及为什么。
`dsh-mneme/test/client.test.js`	新增一例回归锁：找 moreAnchor / 插在它之前 / 对着它幂等 / 老宿主的追加组尾分支必须在。
`dsh-mneme/CHANGELOG.md`	Unreleased 条目。

判据一律走 [class*=] 前缀，与既有 panelRow / regionArea 同一套做法，不写死宿主哈希类名。

验证

npm test：2808 tests / 2807 pass / 0 fail / 1 skipped（新增 1 例）
node scripts/check-sync.js：✓ src/ 与 lib/ 一致（94 个文件）
手工核对的宿主顺序：插件 … SSH → 更多 → 记忆，改后应当变成 插件 … SSH → 记忆 → 更多（issue 里的 DOM dump 直接可对照）

没做的事

没换官方面板注册。issue 里给了另一条路（同时注册 main + sidebar.panellist，进「更多」的固定项），但那是把记忆入口变成正式面板页的语义变更，不是这个 bug 的修法。这里只修位置。
入口依然不在「更多」菜单的可固定项里。若这是想要的（保持低调的浮动入口），到此即可；要改成正式面板另开 issue。

Closes #573

Summary by CodeRabbit

修复
- 调整宽屏侧栏中记忆入口的位置：存在“更多”项时显示在其前方；不存在时仍显示在列表末尾。
- 修复重复设置入口时的位置保持一致。
测试
- 新增回归测试，验证入口排序、重复设置及无“更多”项时的兼容行为。

宿主 0.2.2 起把 PanelMoreMenu 追加进同一个 nav.panelList，组尾不再是面板行。入口仍 appendChild 到末尾就会排到「更多」下面，菜单一展开正好盖住它（#573）。 place() 先找 [class*=moreAnchor]，命中则 insertBefore；没有该行的老宿主原样退回 appendChild。幂等判据同步改成 nextElementSibling === more，稳态下观察器不写 DOM。

Walkthrough

侧栏记忆入口现在优先插入宿主「更多」行之前；找不到该行时，仍追加到列表末尾。新增回归测试覆盖入口位置、重复落位和无锚点时的回退行为。

在移动入口前保存焦点，移动后恢复焦点。

place() 移动入口时，入口内的按钮若持有焦点，焦点会丢失到页面主体。移动会先从父节点移除入口，浏览器随之清除焦点。该情况发生在宿主于入口与「更多」行之间插入面板行时。此时焦点按钮需重新定位。

place() 中共有三处移动入口：list.insertBefore(created, more)、list.appendChild(created) 与 parent.insertBefore(created, target)。三处都需包裹，否则其余两处仍会丢失焦点。

为「更多」行前的落位分支补充执行级测试。

这组断言只检查源码中是否包含指定字符串，不执行 place()。把 if (more) 改成 if (!more) 后，四个字符串仍然存在，测试仍然通过。仓库中没有其他测试执行 place()。因此，落位分支被反转时，该测试无法发现问题。带「更多」行的列表会走追加分支，入口会落在「更多」之后。

建议改为 DOM 级测试：

截取 place 所在的代码块，参照「panel seats」测试的做法，用 new Function 在假 DOM 上执行。截取边界需先确认，因为 place 依赖闭包变量 created、wide 与 region。

假列表需提供 querySelector、insertBefore、appendChild 与 lastElementChild。假入口需提供 parentElement 与 nextElementSibling，因为回退分支会读取 created.parentElement。

断言以下两点：有「更多」行时，入口插在「更多」之前；无「更多」行时，入口追加到列表末尾。
