Steps to reproduce the problem:
1. Install Korean Language
2. Open a new tab and type in Korean
3. Open another new tab and try to type in Korean
The language changes to English by itself while Opera browser works fine. 

What is the expected behavior?
Language shouldn't change while opening new tabs. 

What went wrong?
Here is the issue:
I found out that Chrome cannot keep up the Windows Input Method Editor (IME) for most East-Asian languages when the software or a new tab is reopened in Windows 10 (or maybe even previous versions). 

I've tested the following software to see in which one the keyboard remains in Korean IME mode and which one doesn't hold on to the IME. Here are the results when you open a new tab, page or reopen the software after the Korean IME was already chosen:
1- Microsoft Word: No keyboard / IME change. 
2- Microsoft Excel: Doesn't Hold on to the IME - switches to English
3- Internet Explorer: Doesn't Hold on to the IME - switches to English
4- Firefox browser: Doesn't Hold on to the IME - switches to English
5- Opera browser: No keyboard / IME change.
6- Chrome browser: Doesn't Hold on to the IME - switches to English
7- Notepad: Doesn't Hold on to the IME - switches to English

As we see only Microsoft Word and Opera are holding on to the IME if you open another tab or a new Word page. Basically it's because Windows doesn't reset the language to English on these two apps automatically when they are reopened. Is Opera ahead of Chrome at this point? 
On the other software Windows keyboard language detection is detecting the software language as English so the IME changes by itself to English. 

Knowing these, the only solution for keeping up the IME in Korean language in Chrome was to change the entire Chrome software's language to Korean. So Windows keyboard detector will see Chrome in Korean language and the IME remains Korean. 

We know it's not practical and Chrome is missing something in functioning that Opera doesn't and the IME language shouldn't get changed by opening new tabs or reopening the software. 
First I thought probably because each tab on Chrome has its own individual location on processor/memory, the language changes to English on new tabs, but I am not seeing the same symptoms in my native language Parsi (Persian) keyboard. 

Just wanted to report it to Chrome developers to see if they are able to resolve the issue.
