Marks a frame whose fragment mimetypes were elided by the sender.
Present only when something was actually elided, so a frame that gained
nothing carries no header either. A receiver expands whenever it sees this,
whatever its own options say: the sender has already dropped the bytes, and
the alternative to expanding is delivering chunks with a mimetype the
application never wrote.
