Custom Media Breakpoint Bug in Production

[saragebran]

There are no issues is dev but in production _media-queries.scss builds the breakpoints as
@mediascreen and (...)
instead of
@media screen and (...)
which breaks all the responsiveness is lost.

Is it something in nano-css as part of the CssMinimizerPlugin() ?

This is is happening for me having setup the Hugo template with Netlify. Has anyone else noticed this?
