There are two distinct concepts in copyediting: In the article mutagen bomb victims (IDW), the section header text you edited is more appropriately "Known victims" (sentence case), not "Known Victims" (title case).
 * ("The Quick Brown Fox Jumps over the Lazy Dog"): Capitalizing the first word and all subsequent words except for certain article words, preposition words, and so forth.  This is appropriate for s, and the titles of television shows, films, episode titles, book titles, etc., unless specifically intended to be spelt otherwise.
 * ("The quick brown fox jumps over the lazy dog"): Capitalizing only the first word of a phrase, as if writing a sentence; proper nouns within a sentence case phrase are still themselves individually in title case.  Sentence case is appropriate for article names, section names, possibly infobox fields, and so forth.

As a fellow user and copyeditor, may I request that you take this into consideration, please?
