+ <p>
+ A screen's [=current orientation type|type=] and [=current orientation
+ angle|angle=] is a potential fingerprinting vector. To resist
+ fingerprinting (e.g., in private browsing), user agents MAY:
+ </p>
+ <ol>
+ <li>Restrict the value return by the {{ScreenOrientation/type}}
+ attribute to {{OrientationType/"portrait-primary"}} or
+ {{OrientationType/"landscape-secondary"}} so to match the screen's
+ aspect ratio.
+ </li>
+ <li>Always return `0` for the value of the {{ScreenOrientation/angle}}
+ attribute
```suggestion
attribute.
