Pull Request Overview
This PR fixes an issue with the TabBarView control by restructuring how it handles height constraints and nested tab scenarios. The fix addresses issue #5581 by improving the error handling and layout logic for unbounded height situations.
- Restructured the
TabBarViewwidget logic to properly handle expand properties and avoid layout builder conflicts - Updated integration tests to include a new nesting test case and simplified the basic test structure
- Modified the nested tabs example to reorder content for better demonstration
