This PR addresses the UI test image failures that occurred in the inflight/candidate branch #34294 and includes updates to improve rendering and test stability across platforms.

Controls Handler Registration

  • Simplified the logic for registering handlers for controls like Label, Editor, Picker, RadioButton, and TimePicker in AppHostBuilderExtensions.cs. The new approach registers all fallback handlers together, reducing duplicated code and improving maintainability.

  • In the NavigationRootManager class, the line _rootView.SetTitleBar(null, null); was added in this PR Fix crash when closing Windows based app when using TitleBar #34032 by a contributor due to an AI minor suggestion, but this line causes an issue when swapping pages, so the TitlebarWorksWhenSwitchingPage test fails. Setting SetTitleBar to null is already implemented in the WindowHandler class in the DisconnectHandler method, so I have removed this line _rootView.SetTitleBar(null, null); from the PR 34032.

Image Resave:

Test Stability and Platform-Specific Handling

  • Added a platform-specific ignore for a Shell flyout test on iOS 26 due to a known bug, improving test reliability and clarity about platform limitations.
  • Updated a CollectionView scroll test to wait for specific elements on Windows, ensuring the test works correctly across platforms.

DatePicker Handler Tests

  • Introduced a helper method EnsureDialogCreated in DatePickerHandlerTests.Android.cs to reliably create the native dialog before reading min/max values, addressing issues caused by lazy dialog creation after a recent PR. This helper is now used in relevant tests to improve robustness. [1] [2] [3]
  • Clarified the DatePicker test logic in DatePickerTests.cs to ensure the DateSelected event fires correctly regardless of dialog state, improving test reliability on Android.

[Testing] Fixed Test case failure in PR 34294 - [03/2/2026] Candidate…
2c73f63 
… - 1 (#34334)

This PR addresses the UI test image failures that occurred in the
inflight/candidate branch #34294 and
includes updates to improve rendering and test stability across
platforms.

### Controls Handler Registration

* Simplified the logic for registering handlers for controls like
`Label`, `Editor`, `Picker`, `RadioButton`, and `TimePicker` in
`AppHostBuilderExtensions.cs`. The new approach registers all fallback
handlers together, reducing duplicated code and improving
maintainability.

### 
* In the NavigationRootManager class, the line
_rootView.SetTitleBar(null, null); was added in this PR
#34032 by a contributor due to an AI
minor suggestion, but this line causes an issue when swapping pages, so
the TitlebarWorksWhenSwitchingPage test fails. Setting SetTitleBar to
null is already implemented in the WindowHandler class in the
[DisconnectHandler](https://github.com/dotnet/maui/blob/main/src/Core/src/Handlers/Window/WindowHandler.Windows.cs#L55)
method, so I have removed this line _rootView.SetTitleBar(null, null);
from the PR [34032](#34032).

### Image Resave:
* Resaved images: DownSizeImageAppearProperly,
Material3CheckBoxFeatureTests, Material3CheckBox_DefaultAppearance,
DownSizeImageAppearProperly,
VerifyLinearGradientBrushWithStrokeAndOpacity,
VerifyRadialGradientBrushWithOpacity,
VerifyRadialGradientBrushWithShadowAndOpacity,
VerifyLinearGradientBrushWithOpacity,
VerifyLinearGradientBrushWithShadowAndOpacity,
DarkTheme_VerifyVisualState. These PR fixes address the issues:
#33173,
#31567,
#33590,
#34036
* Added the base images for iOS 26, Mac, and Windows.

### Test Stability and Platform-Specific Handling

* Added a platform-specific ignore for a Shell flyout test on iOS 26 due
to a known bug, improving test reliability and clarity about platform
limitations.
* Updated a CollectionView scroll test to wait for specific elements on
Windows, ensuring the test works correctly across platforms.

### DatePicker Handler Tests

* Introduced a helper method `EnsureDialogCreated` in
`DatePickerHandlerTests.Android.cs` to reliably create the native dialog
before reading min/max values, addressing issues caused by lazy dialog
creation after a recent PR. This helper is now used in relevant tests to
improve robustness.

* Clarified the DatePicker test logic in `DatePickerTests.cs` to ensure
the `DateSelected` event fires correctly regardless of dialog state,
improving test reliability on Android.

### Test Case Organization

* Removed the obsolete `VerifyFlyoutPage_IsEnabled` test and renumbered
the remaining FlyoutPage tests in `FlyoutPageFeatureTests.cs` to
maintain sequential order and consistency.
