For some reason, even when Webpack fails e.g. wrong main.js config,
the preview may continue to print to stdout, which can affect output
when we catch this error and process those errors (e.g. telemetry)
gets overwritten by preview progress output. Therefore, we should bail the preview too.
An example to get into this situation is using a CRA project without @storybook/preset-create-react-app
