  2. Type French text.
  3. Observe whether spellcheck uses French dictionary.

Observed behavior

  • Spellcheck always uses the browser’s default language.
  • Multi-language content cannot be properly spellchecked.

Expected behavior

  • The lang attribute should control the spellcheck language.
  • Spellcheck should use the appropriate dictionary for the specified language.
  • Multi-language content should be properly supported.
