Re: [csswg-drafts] [selectors] Styling Content in <img> Elements (#3730)

This would not be able to happen cross-origin at all, fwiw. Also generally cross-document selector-matching seems like a huge can of worms...

Gecko does have some limited support for styling embedded SVGs using -moz-context-properties: https://developer.mozilla.org/en-US/docs/Web/CSS/-moz-context-properties

But I'm not sure of the history of those and how they work perf-wise and such. Maybe @jwatt can comment?
