Comment (by audrasjb):

 In [changeset:"53869" 53869]:
 {{{
 #!CommitTicketReference repository="" revision="53869"
 Taxonomy: Prevent non string taxonomy names generating warnings or errors.

 This changeset adds an `is_string( $taxonomy )` check to the condition in
 `taxonomy_exists()`, to ensure `false` is returned when the `$taxonomy` is
 not a string.

 Follow-up to [35718].

 Props costdev, peterwilsoncc, mukesh27.
 Fixes #56338.
 See #56336.
