20427	Remove unused _insert_into_post_button() function	SergeyBiryukov	ryan	"`_insert_into_post_button()` is no longer used in core since [18831].

It's a private function which doesn't seem to be used in any plugins, so I guess it can be removed without deprecation."	enhancement	closed	normal	3.5	Media	3.3	normal	fixed	has-patch needs-refresh
