Comment:

 Users with administrator or editor roles are allowed to use HTML in post
 titles. In your case `<banana>` is a HTML tag and will be rendered as such
 by the browser. Browser are also trying to fix invalid HTML and makes it
 `<banana>festi­­val</banana>`.

 If you want to have the tag rendered as a string (and used in the slug)
 you have to use HTML entities: `<banana>`.
