iOS 26 & Xcode 26 - bug with keyboard by WebView

Environment

• iOS 26 (23A343)
• Xcode 26
• Reproduces on device and Simulator

Description

When presenting a SwiftUI WebView (native iOS 26 component) or a WKWebView/UIWebView via UIViewRepresentable, focusing a text field inside the web view and then dismissing it breaks the keyboard layout behavior.

After returning to the main app, tapping any TextField causes the keyboard to cover bottom controls (e.g. buttons). Expected safe area insets are not applied.
The issue is only resolved after closing and reopening the keyboard once.

Steps to Reproduce

1. Open a SwiftUI screen with WebView (via .sheet or NavigationLink).
2. Inside the web view, tap a text field to show the keyboard.
3. Dismiss the web view.
4. Tap a TextField in the main app.

Expected Result

• Layout should adjust correctly.
• Bottom controls stay visible above the keyboard.

Actual Result

• Keyboard covers bottom controls.
• Insets are ignored until the keyboard is dismissed and reopened.

Notes

• Reproduces with:
  • Native SwiftUI WebView (iOS 26)
  • WKWebView and UIWebView via UIViewRepresentable
• Presentation style (.sheet or navigation push) does not matter.

Sample Code

import SwiftUI
import WebKit

struct ContentView: View {
    @State var url: URL?
    @FocusState private var isFocused: Bool

    var body: some View {
        VStack {
            TextField("TextField", text: .constant(""))
                .focused($isFocused)

            Button("HIDE KEYBOARD") { isFocused = false }

            Spacer()

            Button("ACTION") {
                url = URL(string: "https://google.com")
            }
        }
        .sheet(item: $url) { value in
            NavigationStack {
                WebView(url: value)
                    .toolbar {
                        ToolbarItem(placement: .topBarLeading) {
                            Button("CLOSE") { url = nil }
                        }
                    }
            }
        }
    }
}
