Changing textfield font of UISearchBar also changes it's height - swift

Question

I am changing UISearchBar's UITextField font size:
UITextField.appearance(whenContainedInInstancesOf: [UISearchBar.self]).defaultTextAttributes = [.font: UIFont.systemFont(ofSize: 17)]
or
searchBar.searchTextField.font = .systemFont(ofSize: 17)
This is the same font size value as the default. But UISearchBar also changes its height. Looks like it's a little bit bigger than the default height value. How I can fix it?
Default UISearchBar height:
After font size change (pay attention that actual font size is the same as on screenshot above):
UPDATE:
I have a storyboard with UITabBarViewController in it. Then I have two UIViewControllers connected to UITabBarViewController. One of them is empty and another one contains UINavigationController with connected sample VIewController which is UITableViewController. Here is a sample code of test ViewController:
import UIKit
class ViewController: UITableViewController {
private lazy var searchController: UISearchController = {
let searchController = UISearchController(searchResultsController: nil)
searchController.obscuresBackgroundDuringPresentation = false
searchController.searchBar.autocapitalizationType = .none
searchController.searchBar.placeholder = "Search"
searchController.searchBar.barStyle = .black
searchController.searchBar.tintColor = .black
searchController.searchBar.keyboardAppearance = .light
return searchController
}()
override func viewDidLoad() {
super.viewDidLoad()
title = "TEST"
navigationItem.searchController = searchController
navigationItem.searchController?.searchBar.searchTextField.font = .systemFont(ofSize: 17)
definesPresentationContext = true
}
}
