React version: 19.0.0

Steps To Reproduce

  1. use StrictMode
  2. render a list in any way
  3. change the order of the list

Link to code example: codesandbox

The current behavior

When change the order of the list, the list item unmounted and then mounted, except for the first element.

The expected behavior

It should not remount during the update phase.

I test the same code on react 18, which has no problem.
