Comment (by swissspidy):

 It's a bit of a mess it seems.

 `WP_REST_Posts_Controller::update_item()` calls `wp_update_post()`, which
 doesn't allow you to update the post's template to the current value. If
 you'd change that, the meta entry would get updated ''twice''  because the
 `update_item()` method calls
 `WP_REST_Posts_Controller::handle_template()`.

 Ideally, we fix `wp_update_post()`, remove the call to `handle_template()`
 and add a new test for this behaviour.
