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

I tried testing selectionIndicatorImage with UIImage(systemName: "eraser.fill"). Not sure what are the requirements for this image but I think I should see a difference using this sf symbol.
