### Version 2.4.2 ### Reproduction link [https://jsfiddle.net/50wL7mdz/50757/](https://jsfiddle.net/50wL7mdz/50757/) ### Steps to reproduce Access $attrs as object within component context, when no props were provided. ### What is expected? $attrs is an object containing unrecognized props. Therefore I would expect an empty object, when no props are specified on component tag. ### What is actually happening? $attrs is undefined <!-- generated by vue-issues. DO NOT REMOVE -->
