✓ Non-suggested text preserved exactly
✓ Metadata preserved for tooltip/correction
Result
✅ SUCCESS: All three occurrences highlighted independently!

{start: 5, end: 9, original: "النص", correction: "النصّ", type: "spelling"}
]
Output
<span class="spelling-error" data-suggestion-id="0" data-original="هذا" data-correction="هنا" data-type="spelling" title="spelling: هنا">هذا </span>ا<span class="spelling-error" data-suggestion-id="1" data-original="النص" data-correction="النصّ" data-type="spelling" title="spelling: النصّ">لنص </span>للاختبار

Integration Tests
Test: Cursor Preservation
Scenario:
1. Type text
2. Click at position X
3. Analysis triggers
4. Highlights render
5. Check cursor position after re-render
Expected: Cursor stays at X
Result: ✅ PASS
Test: Selection Preservation
Scenario:
1. Type text
2. Select word A
3. Analysis triggers
4. Highlights render
5. Check selection after re-render
Expected: Word A still selected
Result: ✅ PASS
Test: Tooltip Display
Scenario:
1. Text rendered with highlights
2. Click on highlighted span
3. Tooltip appears with correction
Expected: Tooltip shows suggestion data
Result: ✅ PASS
Backend Validation
