This seems reasonable, but can you rebase and make sure tests are passing?

Can you rebase and re-record the snapshot tests to get the travis build to pass?

@sahrens Can you rebase and re-record the snapshot tests to get the travis build to pass?－－this is for @facebook-github-bot? if not be, how can I do? Thank you ~

The bot can't help here - you need to re-record for any change that will affect the snapshot tests. Follow the instructions in the docs here, update your PR, and make sure your Travis build passes and then we'll merge it in:
