[QDyanbing]

说明

• 使用 isReactRenderable 统一判断 tab label、icon、extra content 以及增删图标
• 统一 fallback 行为并支持数字 0 等有效 React 内容
• 将 @rc-component/util 的最低版本提升到 ^1.13.0

验证

• npm run tsc
• npm run lint
• npm test -- tests/index.test.tsx --runInBand

Summary by CodeRabbit

• Bug 修复
  • 修复标签页图标、标签文本、额外内容及操作按钮图标的渲染判断。
  • 现在可正确显示数字等有效的 React 内容，包括值为 0 的图标或内容。
  • 当新增或移除图标为不可渲染值（如空字符串、false 或 null）时，分别回退显示默认的“+”或“×”图标。
  • 下拉菜单中的移除按钮也能正确显示数字图标。

Walkthrough

本次变更将 @rc-component/util 升级到 ^1.13.0，并在标签导航组件中使用 isReactRenderable 判断渲染值。数字等可渲染值可以显示，不可渲染值继续使用默认内容。

Changes

React 可渲染值处理

Layer / File(s)	Summary
新增按钮与附加内容的可渲染判断 package.json, src/TabNavList/AddButton.tsx, src/TabNavList/ExtraContent.tsx	AddButton 和 ExtraContent 使用 isReactRenderable 判断 addIcon、extra 和 content。
标签与移除按钮的可渲染判断及测试 src/TabNavList/OperationNode.tsx, src/TabNavList/TabNode.tsx, tests/index.test.tsx, tests/overflow.test.tsx	TabNode 和 OperationNode 使用 isReactRenderable 判断图标、标签及移除按钮内容。测试覆盖数字 0 和不可渲染值的默认回退。

Estimated code review effort: 2 (Simple) | ~10 minutes

Merge Risk: ⚪ Minimal · up to bb851

Tab rendering now consistently preserves renderable content such as numeric zero while retaining fallbacks for non-renderable values. No current merge-blocking risk is identified.

Poem

小兔检查渲染值，
数字图标清晰现。
真值判断已退场，
不可渲染回默认。
标签导航稳步前。

The implementation changes look semantically reasonable, but the coverage checks are currently failing (codecov/patch and codecov/project). The new icon renderability/fallback paths in OperationNode and TabNode, including numeric zero, are not fully covered.

Please add focused tests for the new branches—especially zero-valued icons and the false/empty/nullish fallback behavior—so the coverage gate passes before this is merged.

[QDyanbing]

Addressed in fa9866a. Focused tests now cover the new OperationNode and TabNode close/remove icon branches, including numeric zero and false, empty-string, and nullish fallbacks. The full test suite (80 tests) passes, and all renderability branches changed by this PR are hit locally.

Thanks for the quick turnaround - the coverage concerns are resolved. One non-blocking test-hygiene suggestion below; happy to merge once it is applied.
