Is there an existing issue for this?

• I have searched the existing issues

Description of the bug

Delete some data from the data input area
See that the search doesn't reflect it
You have to type to actually have the data update

Maybe some debouncing is breaking this

I thought I had it figured out but it's even more complicated, I'm not exactly sure when the data actually updates. Sometimes it does, sometimes it does not.

Thanks for catching this and reporting it! Fixed and deployed now.

It wasn't debouncing (there's no debounce in the playground). Two separate things were going on:

1. The "N items" count was non-reactive, so it never changed even on a clean delete.
2. Editing the data often leaves transiently invalid JSON for a keystroke or two, usually a trailing comma when you delete the last entry. The demo was swallowing that parse error silently, so nothing updated and there was no hint why.

The count updates reactively now, and invalid JSON shows an "Invalid JSON" badge instead of failing quietly. Live on https://fusejs.io/demo.html (you may need a hard refresh).

Great! The reason I couldn't figure out why it's not updating is that I didn't expect a strict JSON, but JS. Thanks for the quick fix.
