Steps to reproduce:
Please install the attached extension in Chrome and click "Allow in Incognito" in the extension details. A new tab page should have a green background. An Incognito window a red one. In Orion its always green, because the object property "tab.incognito" is always false. Btw a switch like "Allow in Incognito" in extension settings should exists, and extensions should not run in incognito windows by default.
Expected behavior:
As used in attached extension "tab.incognito" should be "true" in an incognito window.
Orion and macOS:

macOS 12.0.1
