[Desktop / Bug] Unable to access Tor private window‘s tabs with chrome.tabs API of chrome extensions

[minamotorin]

Description

I‘m developing a Chrome Extension. chrome.tabs.someMethod API doesn‘t work with Tor private window if I allow to the extension to access private window, but chrome.tabs.onSomething will work.

Steps to Reproduce

1. Add the following the test extension to Brave Browser
2. Open brave://extensions/ and move to the test extension page and allow to the test extension to access private window and see the background page
3. Open Tor private window and access some page (or reloading)

• manifest.json:

  {
    "description": "Example of chrome.tabs API with Tor private windo.",
    "manifest_version": 2,
    "name": "Tor private window example",
    "version": "0.0.1",
    "permissions": [
      "tabs"
    ],
    "background": {
      "scripts": [
        "background.js"
      ]
    }
  }

• background.js:

  // Example of chrome.tabs API with Tor private window.
  
  function printTabInfo(id, info, tab){
    console.log(`tab id is ${id}, tab url is ${tab.url}`);
    chrome.tabs.getZoomSettings(id, zoomSettings => console.log(`Zoom settings of tab id ${id}: ${zoomSettings}`)); // Dosen‘t work with Tor private window.
  }
  
  chrome.tabs.onUpdated.addListener(printTabInfo); // onUpdated is work.

Actual result:

Error occured. Unable to access Tor private window‘s tabs with chrome.tabs.getZoomSettings and log said Zoom settings of tab id 318: undefined. Work fine with private window (not Tor).

Expected result:

No error occured and log says Zoom settings of tab id 318: [object Object] just like private window and normal window.
