What is the current behavior? Korean typing is so slow and lagging in Chrome browser. (Firefox & Safari is OK)

Especially, if you hold pressing the backspace key to erase a character, it seems that it does not work properly. It looks like doing nothing.

**If the current behavior is a bug, please provide the steps to reproduce and if possible a minimal demo of the problem. You can use this jsfiddle to get started: **

You can see: https://youtu.be/gnLmiaw7Sf0

The sequence is 'typing and pressing back space. English and Korean with same sequence. English is erased smoothly but Korean is very very slow.

It is tested at https://draftjs.org/

What is the expected behavior?

Works same as English.

Which versions of Draft.js, and which browser / OS are affected by this issue? Did this work in previous versions of Draft.js?

It is tested at https://draftjs.org/ Probably latest version.

Research-Richtung
Investigate the handling of composition events in Draft.js, particularly in the Editor component. Check the Chrome specific behavior for Korean IME.
