I'm trying to customize the appearance of the liquid glass tab bar. Are these APIs deprecated in iOS 26?
UITabBarAppearance:
configureWithOpaqueBackground() -> would be nice to have an option to keep the shape/behavior but have an opaque background.
backgroundColor -> should this be used both for setting the color of opaque background and tinting the liquid glass?
selectionIndicatorTintColor, selectionIndicatorImage -> neither of these seem to do anything on either iOS 18 and 26
UITabBarItemAppearance:
normal.iconColor -> doesn't seem to work, only selected.iconColor
