How to make UINavigationBar shadowImage fixed?

Question

I have a reversed UITableView:

tableView.transform = CGAffineTransform(rotationAngle: -(CGFloat)(Double.pi))

NavigationBar setup:

navigationBar.shadowImage = UIImage()
navigationBar.layer.masksToBounds = false
navigationBar.layer.shadowColor = Assets.Colors.black.color.withAlphaComponent(0.2).cgColor
navigationBar.layer.shadowOpacity = 0.7
navigationBar.layer.shadowOffset = CGSize(width: 0, height: 2.0)
navigationBar.layer.shadowRadius = 5
navigationBar.isTranslucent = false
view.backgroundColor = color

Whenever I scroll to the bottom of my TableView (to the top when inverted), shadow disappears. I want it to be constant (like at the second screenshot).
Is it possible to make UINavigationBar shadow static regardless of TableView scrolling?

How it looks now:
No shadow

How it should be:
With shadow

In iOS15/Xcode13, there is a common problem with the navigation bar's appearance. You can read more here and apply the fixes.
