google chrome - Does content script have access to newtab page?

Question

Updated

Thanks @kofifus for the info, Chrome as of 61 explicitly forbids content scripts on its default new tab page

Say I have the following sample extension, it will output test in console.

manifest.json

{
  "name": "Test",
  "version": "1.0",
  "manifest_version": 2,
  "content_scripts": [
    {
      "matches": [
        "<all_urls>"
      ],
      "js": [
        "content.js"
      ]
    }
  ]
}

content.js

console.log('test');

Will above extension work well in chrome://newtab page?

Some helpful info:

1. I know by default chrome extension can't access to chrome:// pages, and we could change this behavior through chrome://flags/#extensions-on-chrome-urls

2. chrome://newtab in fact is a url like https://www.google.co.jp/_/chrome/newtab?espv=2&ie=UTF-8, so it shouldn't be blocked by above restriction.

3. There are many mouse gestures extension available, like crxMouse, they work well on chrome://newtab page

4. There are also some voices saying it's not allowed to inject content scripts in chrome://newtab, for example, @Xan's comments below this answer and this author's case

So it looks weird as its different behavior across different devices( or settings?). Is there any official statements about whether content scripts can run in chrome://newtab pages? Or is there a setting we could change this behavior?
