It's showing "no preview" for me the whole time on your storybook (private link). Hopefully one of our polymer gurus can give a look!

Confirming this bug still exits with storybook 5.1.0-rc.0

I'm not able to reproduce the behavior in the polymer-cli example. @bennypowers if I could take a look at the example too, I might be able to help here. 🙇

@ndelangen Thanks for writing. I sent you a PM on storybook's discord with the link to the (private for now) storybook. Thanks for the interest

I was unable to reproduce with storybook 5.1.3. Closing for now. If it comes back once I succeed at building newer versions (#7084) I'll reopen

Thanks for reporting @bennypowers 🙇

I sure hope the issues stays closed, but obviously happy to assist if it does crop up again.
