Summary

Looks like in the push to remove deps in #67 , seems like we still need the import-css plugin. Noticed that there was a flickering when changing slides in a project

and was able to confirm that the variable setting the iframe background color does not register now

Details

This is related to this change specifically. I incorrectly assumed :host would pierce the shadow, and it does not. hardcoding the style into the Shadow DOM confirmed restoration of the background color

So likely we will need to re-introduce that plugin as a dependency and part of the setup steps. Not sure to push this out as a patch or semver minor though?
