For some reason this Package does not support borderless windows (called on NSWindow 0x11c627e90 which returned NO from -[NSWindow canBecomeKeyWindow] )

macOS: 13.3.1 (22E261)
XCode: Version 14.3 (14E222b)

App/Window is active, but created from AppDelegate manually:

import SwiftUI
import MacMenuBar

@main
struct PixieApp: App {
    @NSApplicationDelegateAdaptor(AppDelegate.self) var appDelegate : AppDelegate
    
    init() {
        appDelegate.showMainWnd()
        setMenuBar(to: MainMenuBar(appDelegate: appDelegate))
    }
//////
}

This is strange, as app must to have main menu even if there are no windows in the app is active. Something with package is wrong.
