Illegible navigation title when presenting Map view

When building with the iOS 26 SDK (currently beta 4), the navigation title is often illegible when rendering a Map view.

For example, note how the title "Choose Location" is obscured by the map's text ("South America") in the screenshot below:

This screenshot is the result of the following view code:

import MapKit
import SwiftUI

struct Demo: View {
  var body: some View {
    NavigationStack {
      Map()
        .navigationTitle(Text("Choose Location"))
        .navigationBarTitleDisplayMode(.inline)
    }
  }
}

I tried using the scrollEdgeEffectStyle(_:for:) modifier to apply a scroll edge effect to the top of the screen, in hopes of making the title legible, but that doesn't seem to have any effect. Specifically, the following code seems to produce the exact same result shown in the screenshot above.

import MapKit
import SwiftUI

struct Demo: View {
  var body: some View {
    NavigationStack {
      Map()
        .scrollEdgeEffectStyle(.hard, for: .top) // ⬅️ no apparent effect
        .navigationTitle(Text("Choose Location"))
        .navigationBarTitleDisplayMode(.inline)
    }
  }
}

Is there a recommended way to resolve this issue so that the navigation title is always readable?
