Issue typing Korean after two space characters

[slotterbackW]

📝 Provide detailed reproduction steps (if any)

When typing Korean in CKEditor, after typing two spaces vowels stop being combined.

1. Set keyboard language to 2-set Korean
2. Press "d", "k", "t" keys on keyboard
3. Notice vowels are combined into a single character
4. Press space twice
5. Type "d", "k", "t" again.
6. Notice vowels are not combined

✔️ Expected result

The vowels should be combined again, and produce the same character which was produced when typing them before the spaces.

❌ Actual result

The vowels are not combined.

📃 Other details

• Browser: Chome
• OS: MacOS 11.6.2
• First affected CKEditor version: …
• Installed CKEditor plugins: Reproducible on classic editor and possibly others?

Hi, thanks for the report. We are aware of issues with IME and we plan to address them in migration to beforeInput, which is currently very high on our priority list.

The work for this issue and others related is completed in the #16289, and we finalized the round of internal (successful) tests. I encourage everyone to test the PR if you have a chance. It should be merged in the following days, and will be a part of the next release.
