Late-parsed globals are unparsed in static-cached embeds

[croxton]

EE template

{stash:embed
  context="@URI"
  name="test"
  file_name="partials:late"
  process="static"
  parse_stage="both"
} 

partials:late

These "late parsed" variables remain unparsed in the resultant static cached page:

{site_url}
{path="blog"}
