Korean - grid, first character broken

hello

Here is Korea.

When entering Korean into the cell of the grid, the first letter is not normally combined and is broken in chrome.

It seems to be a problem that does not reflect the Asian IME composition.
For example, if you input Korean ‘가’, ‘r ㅏ’ is input.

Is improvement possible?

thank you
