One needs to press Backspace twice to delete the last character from inline input hole in Windows Safari.
Steps to reproduce:
1. Enable and select Korean input method.
2. Type "gks" for 한.
3. Press Backspace 3 times.
Expected results: 한' is divided into 3 syllables, so it should be removed after pressing Delete key 3 times. But now the last consonant, 'ㅎ' still remains.
I could reproduce the same issue with Chinese Simplified IM.
