^{Originally posted by QzCurious May 6, 2024} Though I use IME, but I only learned that it somehow relate to how I type/construct Chinese characters. I don't know it in any technical aspect.

It's recorded from official docs here. What I'm doing is:

1. Click on <SearchField /> and ready for typing
2. Switch IME for typing Chinese characters
3. Start typing some primitives to construct the words "被送出"
4. While I type, you can tell that I'm "constructing" by the underline
5. Whenever I'm done constructing, I press "Enter" to construct/complete the words "被送出"
6. The bug happened

I though this behavior is caused by trigger onSubmit directly by keypress on "Enter" key (Have been discussed a bit on https://github.com/adobe/react-spectrum/discussions/5774#discussioncomment-8310540).

At this point, I'd like to argue again that instead of having a custom onSubmit implementation, not interrupting browser default behavior for "Enter on an input" might be a better approach .

I didn't notice you create a issue for my discussion. I think you can close it as the bug already solved by #6404.
