* #4548: comment ranges inside footnotes and endnotes are kept on read
read_opened read footnotes.xml and endnotes.xml before comments.xml, so
a comment range inside a note looked its id up in an empty comment map
and was dropped. Comments are now read first. read_comments uses nothing
the notes set up.
Regression test: tests/it/note_comments.rs (synthetic markup).
