Korean IME problem in CEP 12 Panel

Dear all,

Hello.

I have a problem with Korean Input in CEP 12 Panel.

When I input Korean in input or textarea tag, a small box which shows the last Korean character occurs at the left top of the screen like below:

I assume this is related to character composition event.

Maybe the event is not in sync between Premiere Pro and the panel.

I found that this problem doesn't occur on CEP 9/10.

I'd like to know whether there is a plan to fix this, or any way to fix this problem.

Thank you.
