[i0rph]

Jodit Version

5.3.21

Browser

Safari

Operating System

Other

React Version

19.2.0

Code to reproduce

import React, { useState, useRef, useMemo } from 'react';
import JoditEditor from 'jodit-react';

const Example = ({ placeholder }) => {
  const editor = useRef(null);
  const [content, setContent] = useState('');

  const config = useMemo(
    () => ({
      readonly: false, // all options from https://xdsoft.net/jodit/docs/,
      placeholder: placeholder || 'Start typings...'
    }),
    [placeholder]
  );

  return (
    <JoditEditor
      ref={editor}
      value={content}
      config={config}
      tabIndex={1} // tabIndex of textarea
      onBlur={newContent => setContent(newContent)} // preferred to use only this option to update the content for performance reasons
      onChange={newContent => {}}
    />
  );
};

Expected behavior

Korean should be typed as user intended.

Actual behavior

On any version of Jodit React (even on Jodit itself), when I trying to type in Korean on iOS, it keeps removing or adding last text.

This bug appears in jodit example page too.

IME composition on iOS is the one class of bug I can't reproduce in automated browsers — composition events don't fire the way a real device fires them. Could you add some detail so I can chase it on hardware: what exactly breaks (characters duplicated? jamo not combining? cursor jumping?), iOS/Safari version, and whether it happens in the plain jodit demo (https://xdsoft.net/jodit/) too or only in your app? If it reproduces on the demo page, it's an editor core issue and that narrows it down a lot.
