Phenomenon

When using a Korean IME (Input Method Editor) in Firefox on Windows, pressing Enter during composition cancels the composition instead of committing it. This breaks the expected IME workflow.

Reproduction example

  1. Create a contenteditable div.
  2. Switch to Korean IME.
  3. Start typing Korean characters (e.g., β€œν•œκΈ€β€).
  4. While the composition is active (characters are still being composed), press Enter.

Observed behavior

  • In Firefox on Windows with Korean IME, pressing Enter cancels the composition.
  • The partially composed characters are lost.
  • The Enter key does not commit the composition as expected.

Expected behavior

  • Pressing Enter during IME composition should commit the composed characters.
  • The composition should complete and the characters should be inserted into the contenteditable.
