Applying formatting in blockquote breaks structure in Firefox

OS: Windows 11 Device: Desktop or Laptop Any Browser: Firefox 120.0 Keyboard: US Status: draft
blockquote formatting structure firefox

Phenomenon

When applying formatting (bold, italic, etc.) to text inside a blockquote in Firefox, the blockquote structure may break. The blockquote may be removed or converted to regular paragraphs.

Reproduction example

  1. Create a blockquote: <blockquote><p>Quoted text</p></blockquote>
  2. Select text inside the blockquote
  3. Apply bold formatting

Observed behavior

  • Blockquote structure may be broken
  • Blockquote may be converted to paragraphs
  • Formatting is applied but structure is lost
  • DOM structure becomes: <p><b>Quoted text</b></p>

Expected behavior

  • Blockquote structure should be maintained
  • Formatting should be applied within blockquote
  • Blockquote should remain as <blockquote>
  • Structure should not break

Browser Comparison

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

Notes and possible direction for workarounds

  • Intercept formatting in blockquote context
  • Apply formatting within blockquote structure
  • Preserve blockquote during formatting
  • Normalize structure after formatting
