progers has just created a new issue for https://github.com/w3c/csswg-drafts:
== [css-contain] Clarification: does content-visibility: hidden affect id references? ==
In https://crbug.com/464210151 we got a bug that boils down to the following testcase:
```
<svg width="100" height="100" style="background: red;">
<rect x="0" y="0" width="100" height="100" fill="url(#lingrad)" />
</svg>
<div style="content-visibility: hidden;">
<svg width="100" height="100">
<defs>
<linearGradient id="lingrad" x1="0" y1="0" x2="0" y2="1">
<stop stop-color="lime" offset="0%" />
<stop stop-color="lime" offset="100%" />
</linearGradient>
</defs>
</svg>
</div>
```
Firefox, Safari: green
Chromium: red
https://drafts.csswg.org/css-contain/#skips-its-contents is the relevant section of the spec, but I don't think the behavior of id references is clear.
