Doesn't animate. Is there a known issue mixing `instantiateViewControllerWithIdentifier` with `presentViewController`? Seeing similar behavior in another app.

- (void)presentAccountChooser
{
    UIStoryboard *storyboard = [UIStoryboard storyboardWithName:@"Main" bundle:nil];
    UINavigationController *navVC = [storyboard instantiateViewControllerWithIdentifier:@"AccountChooserViewControllerNavVC"];
    AccountChooserViewController *accountChooserVC = (AccountChooserViewController *)[navVC topViewController];
    accountChooserVC.accounts = [self.twitterStore systemTwitterAccounts];
    accountChooserVC.delegate = self;
    NSLog(@"modalTransitionStyle %d", self.modalTransitionStyle);
    navVC.modalTransitionStyle = UIModalTransitionStyleCoverVertical;
    navVC.modalPresentationStyle = UIModalPresentationFullScreen;
    [self presentViewController:navVC animated:YES completion:nil];
