Korean input using keyboard on web is malfunctioning when you use space between korean characters

[DrSongTeam]

Entering Korean character using computer keyboard on Web or on Android is malfunctioning. When you enter space after several Korean input, the apps stops running and freeze.
Entering Korean character with phone works.

In flutter Textfield, same thing happens.
I was able to manage this issue in TextField by adding String variable textStr = '';
and added the following code to onChanged method in TextField.
setState( (value) => textStr = textController.text);

Hope this bug in quill editor will be fixed soon.
