`ContextMenu` and `Menu` Item Layout: Icon/Title Order Discrepancy Between System and Custom Apps (iOS 26)

I've observed a difference in the layout of menu items within ContextMenu and Menu when comparing system applications to my own SwiftUI app, specifically concerning the order of icons and titles.

On iOS 26, system apps (as shown in the image in the "System App" column) appear to display the item's icon before its title for certain menu items. However, in my SwiftUI app, when I use a Label (e.g. Label("Paste", systemImage: "doc.on.clipboard")) or an HStack containing an Image and Text, the icon consistently appears after the title within both ContextMenu and Menu items.

I'm aiming to achieve the "icon first, then title" layout as seen in system apps. My attempts to arrange this order using HStack directly within the Button's label closure:

Menu {
    Button { /* ... */ } label: {
        HStack {
            Image(systemName: "doc.on.clipboard")
            Text(String(localized: "Paste"))
        }
    }
    // ...
} label: {
    Text("タップミー")
}

seem to be overridden or restricted by the OS, which forces the icon to the leading position (as shown in the image in the "Custom App" column).

System App	Custom App

Is there a specific SwiftUI modifier, or any other setting I might have overlooked that allows developers to control the icon/title order within ContextMenu or Menu items to match the system's behavior? Or is this a system-controlled layout that app developers currently cannot customize, and we need to wait for potential changes from Apple to expose this capability for in-app menus?

Thanks in advance!
