Manual:$wgRestrictDisplayTitle/pt

Detalhes
Restringe a exibição de títulos para os títulos que normalizam a mesma chave da base de dados que o título da página real. This roughly means that only capitalization variations of the title are accepted. If set to, any display title is allowed. This is not recommended however, as it breaks the wiki convention that a page's title is its name, and thus can be used for linking to it.

Additionally, some inline CSS rules like  which can cause the text to be hidden or unselectable are disallowed.
