This repo demonstrates bug with NextJS not deduplicating POST requests during server action execution after revalidation.

Scenario:

1. Open home page.
2. See 5 identical timestamps.
3. Click Revalidate button.

Expected result: action takes about 500ms, five identical fresh timestamps are displayed.

Actual result: action takes about 2500ms, five unique timestamps are displayed.

Notes:

• issue is not reproducible for request using GET method
• while this repository is using Canary, the issue is also reproducible in latest stable version (15.4.7).
