IME input in `Editor` does not work with React 18's createRoot

[InaGlushkova]

Using the Japanese IME in the Editor's Controlled Mode, the text is finalized while being typed and the text cannot be typed as intended. It occurs when using React 18's createRoot.

Environment to reproduce the issue:

• Firefox 103, Chrome 104 on mac 12.5
• Firefox 104 (Developer Edition) on windows 11

Steps to reproduce the issue:

1. Focus on the editor
2. Switch to Japanese input mode
3. Type "こんにちは" (k o n n n i t i h a)
