Categories do not use the specified {{DISPLAYTITLE:}} everywhere where appropriate, e.g. in the various category headers and page titles (<h1> and <title>):
- Header «Pages in category "categoryname"», message category_header
(e.g. http://en.wikipedia.org/wiki/Category:IPad)
{F3172666}
- Header «Media in category "categoryname"», message category-media-header
(e.g. http://commons.wikimedia.org/wiki/Category:Ffdshow)
{F3172670}
- Page title of edit (action=edit, {{int:editing}}) and history pages (action=history, {{int:history-title}}) for categories and other page
{F3172667}
See also {T26139}, which is related to how the DISPLAYTITLE of page A affects page ¬A, while this report is about the appearance of the title of page A on page A itself (?title=A, ?title=A&action=edit, ?title=A&action=history).
