Pasting content into table cell breaks table structure

Phenomenon

When pasting formatted content into a table cell in Chrome, 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. Paste formatted HTML content into a cell
3. 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
• Pasted content should be within cell
• Structure should be preserved

Browser Comparison

• Chrome/Edge: May break structure (this case)
• Firefox: More likely to break structure
• Safari: Most likely to break structure

Notes and possible direction for workarounds

• Intercept paste in table cells
• Strip block-level elements from pasted content
• Preserve table structure
• Validate structure after paste
