Steps to reproduce

  1. Download attached ‘test.html’ and open it.
  2. Type Korean characters.

In 'test.html’, a timer event will be triggered on ‘compositionstart’ event, then DOM manipulation will be done in the timer event handler.

  • Actual results :
    Composition is broken.

    For example, I already typed ‘간’ and it’s about to type ‘ㅏ’ expecting ‘가나’ as a result.
    But before I type 'ㅏ’, the timer event has been raised and DOM manipulation has been done.
    After I type 'ㅏ’, I can see ‘간ㅏ’ instead of '가나’.

  • Expected results :
    Composition shouldn’t be broken like Chrome and FireFox.
