11166	wp_set_object_terms() Deletes All New Tags	miqrogroove	filosofo	"While working on #10543, I noticed a logic flaw in function wp_set_object_terms().

The call to $wpdb->insert() is logically incoherent with the default argument $append = false.  Any such occurrence results in the inserted tags being deleted, due to failure to modify the $old_tt_ids array."	defect (bug)	closed	normal	2.9	Taxonomy	2.8.4	normal	invalid	needs-patch
