Research direction
Focus on the Settings menu appearance after toggling themes. The bug occurs specifically on iOS 16 when the 'Save and Fill Addresses' setting is enabled. Check the view controller responsible for the Appearance section and ensure menu labels are properly loaded. The XCUITest `testAddressOptionIsAvailableInSettingsMenu` can be used to reproduce. Look at the `O AddressesTests` file for context. The issue may be related to iOS 16 changes in UIAlertController or UIMenu.
