Major Description
In PackageResourceReference.
When a default reference to a minified resource is used (i.e. the resource wasn't mounted) the resource reference name includes '.min'.
When trying to resolve the minified name, another '.min' is appended, resulting in the minified name resolving to 'html5.min.min.js'.
As a result, the PackageResourceReference concludes that the resource was not minified, and adds compression.
