Describe the bug
When multiple editors are mounted at once, they throw flushSync errors.

flushSync was called from inside a lifecycle method. React cannot flush when React is already rendering. Consider moving this call to a scheduler task or micro task.

Similar to #1513.

To Reproduce
@edwandr helpfully created this minimal example that shows the issue. Load the page and then check the browser console.

Misc

Node version: 22.13.0
Package manager: Bun 1.2.1
Browser: Firefox 137
I'm a sponsor and would appreciate if you could look into this sooner than later 💖
