UIAlertAction.isEnabled = false Has No Visual Effect on iOS 26 (Action Still Looks Enabled)

Hi all,

I'm running into a UIKit issue specific to iOS 26 (Xcode 26 Beta 4) where UIAlertAction buttons that are disabled using .isEnabled = false do not appear visually disabled. The alert still shows the action with full opacity and default styling, making it look like the button is tappable — even though it isn't.

❗ Issue: On iOS 26, disabled actions in UIAlertController no longer appear dimmed or inactive. This is a visual regression compared to iOS 18 and earlier, where disabled actions would automatically appear grayed out and visually distinct.

We'd appreciate if you could file a bug report for this, along with a small test project that shows the issue. Please post the FB number here for the record.
