Such a file's PDF part is a placeholder page, which was refused. When
the file carries editing data, it now opens from that alone: its
structure as a PDF-compatible file's, its point type made from the text
document, and type it can't make (area type, type on a path) left out
with a note that marks the import as lossy. Without editing data, or
with pages picked or layers off, the placeholder is refused as before;
damaged editing data says so.
The page-order note is no longer given when the page has no type.
