The CSS Working Group just discussed ``[css-color-adjust-1] `color-scheme` should affect embedded iframes``.

<details><summary>The full IRC log of that discussion</summary>
&lt;dael> Topic: [css-color-adjust-1] `color-scheme` should affect embedded iframes<br>
&lt;dael> github: https://github.com/w3c/csswg-drafts/issues/4772<br>
&lt;dael> fantasai: Has normal and other values like darka nd light. Since iFram has change parent and it has different color scheme then main page you can't see iFrame content. Raised that non-normal should cause iFrame to have opaque BG<br>
&lt;dael> fantasai: Whatever webpage is in that frame assumes a different bg then has on own<br>
&lt;dael> chrishtr: and iFrame could override it<br>
&lt;dael> fantasai: iFrame can't choose transparent if we make not transparent, right? Original is transparent and canvas is color<br>
&lt;dael> chrishtr: Canvas behind html element should be opaque<br>
&lt;dael> fantasai: I think<br>
&lt;dael> chrishtr: bg of html element?<br>
&lt;dael> fantasai: Have to change computed of bg color property. initial value is transparent<br>
&lt;dael> chrishtr: I thought for root going to dark theme cause bg of root to change in ua stylesheet. no?<br>
&lt;dael> fantasai: I think it's defined as canvas changes. Could change definition<br>
&lt;dael> chrishtr: Maybe needs more research<br>
&lt;dael> fantasai: kay<br>
&lt;dael> astearns: Research on whats overwritten?<br>
&lt;dael> chrishtr: Yeah. Need to make so dev overwrite it. need to research what spec says<br>
&lt;fantasai> https://drafts.csswg.org/css-color-adjust-1/#preferred<br>
&lt;dael> astearns: Okay, will leave be. I'll remove agenda tag. Once there's a prop please add the tag back<br>
