terminal color goes wrong after spawn

[ui3o]

Syndrome

On windows after spawn the terminal color are not displayed well.

• Node.js Version: v12.19.0
• OS: windows 10
• Scope (install, code, runtime, meta, other?): runtime
• Module (and version) (if relevant): spawn

✔ The first colored line display well but after the spawn
✖ The second colored line wrong

const { spawn } = require('child_process');

async function test() {
    console.log('\x1b[36m%s\x1b[0m', 'I am cyan');
    await run('echo Hello world!');
    console.log('\x1b[36m%s\x1b[0m', 'I am cyan');

    async function run(scrpt) {
        const cmd = spawn('bash', ['-c', scrpt], { stdio: 'inherit' });
        return new Promise((resolve) => {
            cmd.on('close', (code) => resolve(code));
        });
    }
}

test();

• Cygwin is installed
• bash is available on the path

Anybody knows what is wrong with this code?

Thank you!

This question is idle and left unanswered for years now.

• Does the behavior persist if you upgrade to a new version of Node.js? This reported version is end of life.
• Have you attempted to ask this question within other communities, such as stackoverflow?

I am going to circle back in a couple weeks to see if we can close as no-longer relevant.

FWIW, I ran the above in a Node 16.X REPL and got correct behavior:
