[BUG] Screenshot of CJK languages from a Docker container is not working correctly

Context:

Full page screenshots of CJK (Chinese, Japanese, Korean) languages are not working when the Playwright script is running in a Docker container.

I’m testing with taking a screenshot of WordPress.com’s Japanese language signup page at the location https://wordpress.com/start/ja with the following command:

await page.screenshot( {
    path: `start_ja.png`,
    fullPage: true,
    type: 'jpeg',
    quality: 20,
} );

This works well when I run the script on my local MacOS:

However, when the script runs from a Docker container, the screenshot looks like this:

Our custom Docker image used node:16.13.2-buster as the base, which is in turn based on Debian. From my experiments so far, it appears that installing fonts-noto resolves the problem.
