BUG

Provide detailed reproduction steps (if any)

You need to have Korean keyboard - I've used 2-set Korean layout

1. Open editor: https://cdn.ckeditor.com/4.9.0/full-all/samples/
2. Insert table with at least 2 columns
3. Put cursor in 2nd column.
4. Start typing with Korean keyboard letters: ㅎ ㅏ ㄴ (g, k, s - on US layout) it should generate sign 한

Expected result

한 is always generated when ㅎ ㅏ ㄴ are typed in editor

Actual result

ㅎ ㅏ ㄴ remain not transformed

Other details

• Browser: Chrome
• OS: MacOS
• CKEditor version: 4.9.0
• Installed CKEditor plugins: full-all
