Fixed reset all function:
- Fix section-reset event handler to call updateSectionContent instead of non-existent updateTextareaContent
- Ensure proper DOM updates when sections are reset
Fixed image changing functionality:
- Improve image replacement flow with proper DOM updates
- Add safety checks for section retrieval after content updates
- Ensure updateSectionContent is called for immediate DOM reflection
Added comprehensive test suite to verify image functionality works correctly.
All functionality now working as expected.
