Description

[Writing on behalf of Chrome Security and Privacy teams. CC\ @camillelamy ]

The explainer states this as a goal:

Provide access to the color values of one or more user-selected pixels, including pixels rendered by different origins, or outside of the browser.

However, it is preferable to restrict API access only to the page content area only. Access to the browser window/controls area, or area outside of the browser could make clickjacking attacks possible; and potentially reveal fingerprintable information about the user (e.g. OS preferences).
