Empty elements accumulate after removing formatting in Safari

Phenomenon

When removing formatting (bold, italic, color, etc.) in Safari, empty wrapper elements accumulate in the DOM. These empty elements cause layout issues and bloat the HTML significantly.

Reproduction example

1. Apply multiple formatting to text
2. Remove formatting one by one
3. Observe the DOM structure

Observed behavior

• Empty <span>, <b>, <i> elements remain
• Empty elements with style attributes remain
• DOM becomes heavily bloated
• Layout has unexpected spacing

Expected behavior

• Empty elements should be removed
• DOM should be clean
• No unnecessary elements should remain
• Structure should be normalized

Browser Comparison

• Chrome/Edge: May leave some empty elements
• Firefox: More likely to leave empty elements
• Safari: Most likely to accumulate empty elements (this case)

Notes and possible direction for workarounds

• Implement aggressive cleanup logic
• Remove all empty formatting elements
• Normalize DOM structure regularly
• Clean up after each formatting operation
