Describe the Bug

Next only correctly bundles / builds Tailwind css for dev / if next js is run as a server. it appears to fail to correctly export tailwind styles in the static export with no errors.

Expected Behavior

Download the Next JS & Tailwind CSS example template.
cd into directory, run yarn next build && yarn next export
there are no styles on the resulting html file.
