Comment (by azaozz):

 > ...is used to sanitize text input, but the function actually assumes the
 field is a string.

 Right, a "text input" is always a string. This is clearly documented in
 the docblock :)

 I'm thinking this should be `wontfix`. A well-documented function
 expecting an argument of specific type should not be checking if that
 argument is actually of that type (unless we want to throw a "Doing it
 wrong?).

 At most we can probably cast to a string to prevent warnings, although
 these warnings may be helpful to notice errors while developing plugins.
