Original GitHub issue: https://github.com/AppFlowy-IO/AppFlowy/issues/8180

Bug Description

When using AppFlowy with the macOS default Japanese IME (Apple Japanese Input), I encountered an issue with text conversion.

If I try to convert two phrases at once, the first phrase is unexpectedly replaced by the second one.
For example:

Input: ごはんたべたい
Expected: ご飯食べたい
Actual: 食べたい食べたい

How to Reproduce

Type a Japanese sentence with two phrases (e.g., ごはんたべたい).
Convert them together.
The first phrase is replaced by the second.

Expected Behavior

I’d greatly appreciate it if this IME-related issue could be reviewed.
Thank you very much for your amazing work on AppFlowy!

Operating System

sequoia 15.6

AppFlowy Version(s)

0.9.7

Screenshots

No response

Additional Context

The same behavior occurs even when live conversion is disabled.
It seems AppFlowy has difficulty handling phrase-by-phrase conversion with the macOS IME.

Can you upload a video demonstrates the typing process? You can check my video. I'm not sure if I'm typing it correctly.

Thank you very much for checking this! 🙏
Yes, I also confirmed that if I convert the phrases separately, there is no issue.

However, the problem occurs when I try to convert them together in one step.
For example:

Input: ごはんたべたい
Expected: ご飯食べたい
Actual: 食べたい食べたい

So it seems this bug happens only when multiple phrases are converted at once.
Hope this clarification helps! And again, I really appreciate your kind support and the amazing work on AppFlowy.

@tkymatwork thanks for the explanation. I can reproduce it by typing 'gohantabetai' and then converting them together.
