Re: [csswg-drafts] [cssom-view] Add segments property to visual viewport (#9237) (#9285)

Privacy section in the [explainer](https://github.com/WICG/visual-viewport/blob/gh-pages/segments-explainer/SEGMENTS-EXPLAINER.md) indicates that segments will return null when called from within an iframe and explains how this prevents using the API as a fingerprinting vector from cross origin iframes.

A concern I have is accessing the segments through [CSS media queries](https://developer.mozilla.org/en-US/docs/Web/CSS/CSS_media_queries/Using_media_queries#targeting_media_features). Having CSS API in iframes might enable this type of fingerprinting. Is disabling CSS media queries for the segments feasible?
