On iOS 16, the nav bar itself is transparent, so the container view controller’s background is visible. The color of that view wasn’t being updated, which resulted in the nav bar appearing the wrong color. A few view controllers worked around this by manually updating just the background color to the same value used by the table view. It seems cleaner to re-apply the overall styling when the theme changes.
