I’m a Japanese user. I have the same problem with converting Hiragana into Kanji (Chinese character).
The predictive transformation window of the IME overlaps the character.
the predictive window should be like this.
Besides, after converting characters, the prompt automatically moves to the editor from the title bar. Obsidian copies title letters to a note without permission.
