Reproducible Demo

Problem occured here: https://github.com/deepakjois/deepakjois.com/commit/f02c486dac3b03e3118b68205310eb09cce9e186

I was able to make it go away after downgrading react-scripts to 1.0.7. So far I am able to reproduce this reliably in three independent projects, including the one I created using steps above under “Steps to Reproduce”

Random guess. Can you try reverting change from https://github.com/facebookincubator/create-react-app/pull/2430 locally? I think this might have been it.

Confirming it’s fixed in v1.0.9, thanks!
