[Next] Feedback plugin tears down other instances

[chrisvxd]

Description

In scenarios where multiple feedback plugins exist on the page, tearing down one instance may tear down other instances. This is problematic if the tear-down occurs during a drag, as the feedback styles are removed.

Environment

• dnd-kit version: 0.1.17

Steps to reproduce

1. Create two instances of dnd-kit
2. Add an onDragStart callback to the first instance
3. In the onDragStart callback, trigger a state change that causes the second instance to unmount and tear down

Sandbox: https://codesandbox.io/p/sandbox/dnd-kit-feedback-plugin-tear-down-g2nt3j

What happens

The dnd-kit <style> attribute used by the active Feedback plugin is removed mid-drag, causing the drag to render incorrectly.

What I expect to happen

Unmounting the second instance of dndkit to have no affect on the first instance.
