Liquid glass: UIPageViewController inside UITabbarController adding blur effect always in iOS26

When using UIPageViewController inside a UITabBarController on iOS 26 with Liquid Glass adoption, visiting the PageViewController tab applies a blur effect to the navigation bar and tab bar even though the current child view controller of the pageView is not scrollable and does not reach behind these bars.

Questions:

  1. Is this the expected behavior that the pageview's internal scroll view causes the bars to blur regardless of the page view's child content’s scrollability?

  2. If so, is there an official way to make the blur effect appear only when the pageview's current child view controller actually scrolls behind the navigation bar or tab bar, and not in static cases?

Tried the same in SwiftUI using TabView and TabView with page style. Facing the same issue there as well.

Sample screenshots for reference,

Sample SwiftUI code,

struct TabContentView: View {
    var body: some View {
        TabView {
            // First Tab: Paging View
            PagingView()
                .tabItem {
                    Label("Pages", systemImage: "square.fill.on.square.fill")
                }

            // Second Tab: Normal View
            NavigationStack {
                ListView()
            }
            .tabItem {
                Label("Second", systemImage: "star.fill")
            }
            
            // Third Tab: Normal View
            PageView(color: .blue, text: "Page 3")
                .tabItem {
                    Label("Third", systemImage: "gearshape.fill")
                }
                
        }
        .ignoresSafeArea()
    }
}

struct PagingView: View {
    var body: some View {
        TabView {
            PageView(color: .red, text: "Page 1")
            PageView(color: .green, text: "Page 2")
            PageView(color: .blue, text: "Page 3")
        }
        .tabViewStyle(.page) // Enables swipe paging
        .indexViewStyle(.page(backgroundDisplayMode: .always))
        .ignoresSafeArea()// Dots indicator
    }
}

The heavy blur may be caused by the backgroundColor of the UIPageViewController, which is default black. Changing that to another color may fix the problem, at least that did it for me.
