[Bug] SemanticHeading limitations

[rachelkang]

Description

SemanticProperties.HeadingLevel doesn't work when applied to certain controls like SearchBar and ContentPage.ToolbarItem. While it doesn't work for SearchBar, the app crashes when applied to ToolbarItem.

Investigated only on Android

Steps to Reproduce

1. Open .NET MAUI sln on recipes branch
2. Set SemanticProperties.HeadingLevel on the SearchBar in StartingPage.xaml
3. Set SemanticProperties.HeadingLevel on the ToolbarItem in MyRecipesPage.xaml
4. Deploy app to Android physical device
5. Turn on TalkBack
6. Activate Headings mode if not already activated (use three finger horizontal swipe gears)
7. Swipe up/down to navigate Headings on StartingPage - SearchBar will not be reached
8. Navigate to MyRecipes page - app will crash

Expected Behavior

SemanticProperties.HeadingLevel should be applicable to ToolbarItem, as it functions with Button, a similar control. Whether it is applicable to other controls like SearchBar should be clarified and accurately reflected (in intellisense, for example).

Actual Behavior

SemanticProperties.HeadingLevel doesn't work for SearchBar and ToolbarItem.

Hi, @QianaJiao - I've tested again on .NET 8 and can confirm this is still an issue. While it doesn't crash, heading is not supported on searchBar or toolBarItem.

The repro project referenced is at https://github.com/rachelkang/recipeSearch

That being said, please don't worry about re-validating this issue as I'm on the .NET MAUI team and have validated that it is. Thank you!
