Yes, I saw that:

A FontFaceSet is pending on the environment if any of the following are
true:


   - the document is still loading
      - the document has pending stylesheet requests
      - the document has pending layout operations which might cause the
      user agent to request a font.

 None of those are true if a document still needs layout after all the
fonts are downloaded.
