Description

no-open option that is described in the help of the preview command is currently not working (throwing error since the validation expects a "open" boolean value)

Thanks for the PR. FWIW this bug is from thinking like we're using yargs-parser, with the built-in parseArgs not working the same.

We'll merge this in as-is so you can use this fix immediately, but I'm going to pivot to yargs-parser later today.
