`process.execArgv` does not include `--watch` or `--watch-path` options or their values on Windows

Version

v24.11.0

Platform

Microsoft Windows NT 10.0.19045.0 x64

Subsystem

process

What steps will reproduce the bug?

1. Create a build.js file:

/** @file build.js */
import { execArgv } from "node:process";
console.warn(execArgv);

2. Create an empty file named template.html (content does not matter).

3. Run the following command:

(node --watch-path=template.html build.js & node --watch-path template.html build.js & node --watch build.js) > /dev/null

How often does it reproduce? Is there a required condition?

Always reproducible when --watch or --watch-path options are specified on the node command line.

What is the expected behavior? Why is that the expected behavior?

Expected output:

[ '--watch-path=template.html' ]
[ '--watch-path', 'template.html' ]
[ '--watch' ]

According to Node.js documentation, process.execArgv should contain the Node options passed before the script name.

What do you see instead?

Additional information

Bash is installed on my Windows system. I used it in the reproduction steps because it makes it easier to chain blocking commands and run them in the background compared to PowerShell or Command Prompt.
Press Ctrl+C to terminate all background processes at once.

Inizia eseguendo il comando di riproduzione Windows e ispezionando il modo in cui process.execArgv gestisce le opzioni --watch e --watch-path prima del nome dello script. La correzione è completa quando entrambe le forme delle opzioni e i relativi valori compaiono in process.execArgv come mostrato nell’output previsto, preservando al contempo il comportamento dei tre comandi forniti.
