Discription Issue

In React DevTools, the key for Server Components was not consistently visible or properly tracked during component reordering. This made it difficult to debug and maintain the identity of Server Components during reconciliation. The key was not included as part of the ReactComponentInfo, causing issues when components were reordered or rerendered, and DevTools couldn't identify them correctly.

Solution

This issue has been resolved by explicitly passing the key as part of the ReactComponentInfo for Server Components. This ensures that the key is tracked and visible in DevTools, aiding in debugging and preserving the identity of components during reconciliation.

Impact

Developers can now view the key of Server Components in the React DevTools.
The key is correctly passed through to child components, ensuring proper component identity is preserved during reordering.
The reconciliation process now uses the key to maintain instance equality for Server Components, preventing unexpected behavior during re-renders.
