Version

2.5.2

Reproduction link

https://vuejs.org/v2/examples/

Steps to reproduce

在created回调方法里面写一个setTimeout 模拟，抛出error，errorCaptured无法捕捉，如果是同步throw new Error() 就能捕获

What is expected?

errorCaptured能捕获异步promise内部抛出的错误，

What is actually happening?

不能捕获error

文档明确写了异步错误无法捕捉，要你自己处理。这是 js 的语言机制决定的。
