Comment:

 In [changeset:"56115" 56115]:
 {{{
 #!CommitTicketReference repository="" revision="56115"
 General: Ignore invalid types for the '_wp_http_referer' URL query
 variable.

 It's expected that this query variable contains a string when it's set,
 but it's possible for its type to be something else such as an array.
 Ignoring non-string values prevents cascading errors when its value is
 passed through functions that expect a string.

 Fixes #57670
