### Version 1.0.0-beta.29 ### Reproduction link [https://gist.github.com/dmattia/5b99dc2584ec8241f84b30b5476b6ff3](https://gist.github.com/dmattia/5b99dc2584ec8241f84b30b5476b6ff3) ### Steps to reproduce Run the linked test. The first two tests pass as expected, but the third test fails because: `Injection "val" not found` ### What is expected? I would expect that using a parentComponent would inject data to the component being mounted. ### What is actually happening? The only injected values to the child component are those that are passed explicitly through the `provide` option during mounting. <!-- generated by vue-issues. DO NOT REMOVE -->
