How to get UIFont to respect preferredContentSizeCategory in a Mac Catalyst app?

I have an iOS app that relies on dynamic text size such that all fonts in the app respect the user's setting of Text Size in the iOS Settings app.

This app also runs on macOS via Mac Catalyst. But until macOS 14 Sonoma, there was no Text Size setting in the macOS Settings app. But even as of Sonoma, the Text Size setting isn't usable by 3rd party apps. And Sequoia doesn't seem to change that.

As a work around, my Mac Catalyst app provides its own Text Size setting. I was able to make it work by providing my own UIApplication subclass and overriding preferredContentSizeCategory. Under macOS 12 to macOS 14, this workaround works just fine and all fonts in the app created with code such as UIFont.preferredFont(forTextStyle:) gives appropriately sized fonts based on the overridden content size category.

However, this workaround stopped working with macOS 15 Sequoia. I've also tried code such as:

self.window.traitOverrides.preferredContentSizeCategory = myCustomSizeCategoryValue

and

self.window.maximumContentSizeCategory = myCustomSizeCategoryValue
self.window.minimumContentSizeCategory = myCustomSizeCategoryValue

in the scene delegate but that made no difference.

Is there any way to get code such as UIFont.preferredFont(forTextStyle:) to return an appropriately sized font based on some app provided content size category in a Mac Catalyst app running under macOS 15?

It sure would be nice if Mac Catalyst apps automatically responded to the macOS Text Size setting under Settings -> Accessibility -> Display -> Text Size just like a native iOS app.
