I think the missing plugin is 
babel-plugin-transform-inline-imports-commonjs but when using that, we 
get the following error during build. See babel7 branch (this plugin is 
not yet added there).

[18:14:20] Error: Error: No substitution given for "$0". If this is not 
meant to be a
            placeholder you may want to consider passing one of the 
following options to @babel/template:
            - { placeholderPattern: false, placeholderWhitelist: new 
Set(['$0'])}
            - { placeholderPattern: /^$0$/ }
