…n to 9.0.120 (#32614)

Backport of #32612 to release/10.0.1xx-sr1

/cc @PureWeen

Eliminated the coercion logic that set RadioButton.Value to the instance when null, allowing Value to be explicitly set to null. Updated related unit test to reflect the new behavior.

Replaces direct access to options.SelectionLimit with a local variable that defaults to 1 if options is null. Updates all relevant checks and method calls to use the new variable, improving null safety and code clarity.

#32635)

* Add predictive back gesture support for Android 13+

Introduces a unified HandleBackNavigation method to centralize back navigation handling and integrates Android 13+ predictive back gesture callbacks with MAUI lifecycle events. Predictive back is registered and unregistered appropriately, ensuring custom back handling works with system back gesture animation.

* Fix predictive back callback registration and resource management

- Fix potential double registration by checking if callback is null before creating/registering
- Add Dispose() call in OnDestroy() to prevent memory leaks
- Change field type to concrete PredictiveBackCallback for better performance (CA1859)
- Add comment explaining PRIORITY_DEFAULT value

These changes address code review feedback while maintaining the PR's core functionality.

* Simplify code to reduce nesting

### Description of Change

On iPadOS 26.1+, `TabbedPage` crashes with `NullReferenceException` in
windowed apps < 667pt width. iOS 26.1 introduced early
`ViewDidLayoutSubviews()` calls during `UITabBarController` base
constructor execution for narrow viewports, before `_viewHandlerWrapper`
initialization completes.

**Fix:** Add null-conditional operator to `Element` property getter:

```diff
- public VisualElement Element => _viewHandlerWrapper.Element ?? _element?.GetTargetOrDefault();
+ public VisualElement Element => _viewHandlerWrapper?.Element ?? _element?.GetTargetOrDefault();
```

The existing `if (Element is IView view)` guard in
`ViewDidLayoutSubviews()` handles null safely.

… and NavigationPage (#32798)

* Initial plan

* Implement improved fix for iOS 26 TitleView covering content issue

- Added CreateTitleViewContainer helper method to reduce code duplication
- Improved iOS 26+ detection with proper fallback when navigation bar frame unavailable
- Set frame origin to (0,0) instead of preserving potentially uninitialized X/Y values
- Added comprehensive XML documentation explaining iOS 26 workaround
- Added test case and UI test for Issue32287

This implementation addresses the critical issues identified in PR #32337 review:
- Eliminates silent failure by providing fallback to standard constructor
- Clarifies frame positioning logic with explicit (0,0) origin
- Reduces code duplication through helper method
- Adds proper documentation for maintainability

* Apply iOS 26 TitleView fix to NavigationPage

Extended the iOS 26+ TitleView fix to NavigationPage in addition to Shell:

1. Added CreateTitleViewContainer helper method to centralize container creation
2. Added Container constructor overload accepting navigation bar frame for iOS 26+
3. Refactored Container initialization to use InitializeContainer method
4. Updated ToolbarHeight to use actual navigation bar height when available
5. Eliminated hardcoded 44pt height assumption for iOS 26+

This ensures both Shell and NavigationPage TitleView implementations handle iOS 26 layout changes consistently, preventing TitleView from covering page content.

* Enhance Issue32287 test with rotation and dynamic content size changes

Extended the Issue32287 test based on review feedback:

1. Added rotation test to verify TitleView behavior in landscape mode
2. Added dynamic font size change tests to verify container tracks nav bar changes
3. Added buttons to increase/decrease TitleView font size
4. Added x:Name to TitleLabel for programmatic access
5. Created placeholder snapshot image for test validation
6. Wrapped rotation tests with TEST_FAILS_ON_WINDOWS && TEST_FAILS_ON_CATALYST

Tests now comprehensively verify that TitleView container correctly tracks
navigation bar frame changes without covering content in all scenarios.

* - update tests

* Add NavigationPage equivalent tests for Issue32287

Created comprehensive NavigationPage tests mirroring the Shell tests:

1. Issue32287NavigationPage.xaml - NavigationPage with custom TitleView
2. Issue32287NavigationPage.xaml.cs - Code-behind with font size controls
3. Issue32287NavigationPage.cs - UI tests matching Shell test scenarios:
   - Basic test verifying TitleView doesn't cover content
   - Dynamic content size change test
   - Landscape rotation test (iOS/Android only)
4. Created placeholder snapshot image for visual validation

Tests verify that the NavigationPage Container fix handles iOS 26+ layout
changes consistently with Shell, preventing TitleView from covering content.

* Fix NavigationPage XAML structure and add platform-specific comments

Fixed XAML parsing error and addressed PR review feedback:

1. Changed Issue32287NavigationPage from NavigationPage to ContentPage
   - NavigationPage cannot have content directly set in XAML
   - NavigationPage.TitleView is an attached property set on ContentPage
   - Updated base class from NavigationPage to ContentPage

2. Added explanatory comments for platform-specific conditionals
   - Documented that rotation tests only work on iOS/Android
   - Explained SetOrientationLandscape/Portrait not supported on Windows/Catalyst
   - Applied to both Issue32287 and Issue32287NavigationPage test files

Fixes XAML error: "Cannot set the content of NavigationPage as it doesn't
have a ContentPropertyAttribute"

* - fix navigation page

* Delete src/Controls/tests/TestCases.iOS.Tests/snapshots/ios/CustomTitleViewDoesNotCoverContent.png

* Delete src/Controls/tests/TestCases.iOS.Tests/snapshots/ios/Issue32287NavigationPageCustomTitleViewDoesNotCoverContent.png

* - fix tests and add suggested fix

* Remove all test files from PR

Deleted all Issue32287 test files as requested:
- Issue32287.xaml and Issue32287.xaml.cs (Shell tests)
- Issue32287NavigationPage.xaml and Issue32287NavigationPage.xaml.cs (NavigationPage tests)
- Issue32287.cs and Issue32287NavigationPage.cs (UI test implementations)

The PR now contains only the iOS 26 TitleView fix implementation without test coverage.
