beginWork和completeWork的疑问

看图上所示的每个component都会执行到beginWork和completeWork，但实际上并不是这样的
completeWork只有在child没有的时候才会执行，然后找到fiber树上一个有slibing的组件执行beginWork
这样并不是所有组件都会有completeWork

尝试打印了下自己的代码大概如下

beginWork App
scheduler.development.js:468 beginWork RecoilRoot
scheduler.development.js:468 beginWork RecoilRoot_INTERNAL
2scheduler.development.js:468 beginWork undefined
scheduler.development.js:468 beginWork Batcher
scheduler.development.js:468 completeUnitOfWork Batcher
scheduler.development.js:468 beginWork GlobalThemeProvider
scheduler.development.js:468 beginWork undefined
scheduler.development.js:468 beginWork ThemeProvider
2scheduler.development.js:468 beginWork undefined
scheduler.development.js:468 beginWork CssBaseline
scheduler.development.js:468 beginWork LanguageProvider
scheduler.development.js:468 beginWork undefined
scheduler.development.js:468 beginWork ThemeProvider
scheduler.development.js:468 beginWork undefined
scheduler.development.js:468 beginWork Initer

scheduler.development.js:468 beginWork undefined
scheduler.development.js:468 beginWork AxiosIniter
