Editing table cell content breaks table structure in Safari

Phenomenon

When editing text within a table cell in Safari, the table structure may break. Cells may be removed, rows may be deleted, or the table may become malformed.

Reproduction example

1. Create a table: <table><tr><td>Cell 1</td><td>Cell 2</td></tr></table>
2. Edit text in a cell
3. Apply formatting or delete text
4. Observe table structure

Observed behavior

• Table cells may be removed
• Rows may be deleted
• Table structure becomes malformed
• DOM structure breaks

Expected behavior

• Table structure should be maintained
• Cells should remain intact
• Rows should not be deleted
• Structure should be preserved during editing

Browser Comparison

• Chrome/Edge: Generally maintains table structure
• Firefox: May break structure occasionally
• Safari: Most likely to break structure (this case)

Notes and possible direction for workarounds

• Intercept editing operations in table cells
• Prevent operations that break structure
• Validate table structure after operations
• Restore structure if broken
