Re: [csswg-drafts] [css-sizing][responsive-frame] Should `frame-sizing` apply to `<object>` elements? (#13584)

The CSS Working Group just discussed ``[css-sizing][responsive-frame] Should `frame-sizing` apply to `<object>` elements?``, and agreed to the following:

* `RESOLVED: frame-sizing doesn't apply to <object> / <embed>`

<details><summary>The full IRC log of that discussion</summary>
&lt;emilio> koji: so the other issue is whether it should apply on `&lt;object>` / `&lt;embed>`. For now we want to apply only to `&lt;iframe>`<br>
&lt;emilio> q+<br>
&lt;emilio> Rossen: HTML seems to trend in that direction<br>
&lt;Rossen> ack emilio<br>
&lt;TabAtkins> emilio: seems fine, but can you remind me... is it frame-sizing: content?<br>
&lt;TabAtkins> TabAtkins: something liek that<br>
&lt;TabAtkins> emilio: i guess it's not a big issue to add object in the future, or do frame-sizing:none on an object/embed with SVG...<br>
&lt;TabAtkins> emilio: so should the initial value be 'auto'? so we can make 'none' work in the future?<br>
&lt;TabAtkins> emilio: 'auto' just seems more future proof<br>
&lt;TabAtkins> fantasai: i think since it's the initial value we can probably swap it in or out<br>
&lt;emilio> fantasai: we can probably swap the initial value in or out<br>
&lt;emilio> koji: there's an issue about auto from the january f2g<br>
&lt;iank_> https://drafts.csswg.org/css-sizing-4/#responsive-iframes<br>
&lt;emilio> f2f*<br>
&lt;koji> https://drafts.csswg.org/css-sizing-4/#responsive-iframes<br>
&lt;Rossen> Jan 27: RESOLVED: Define frame-sizing with various height and with keywords, with default of auto<br>
&lt;TabAtkins> (initial value is 'auto', there isn't a 'none' value at all yet)<br>
&lt;TabAtkins> emilio: okay, so if we want to add 'none' in the future that'll be safe<br>
&lt;emilio> PROPOSED: frame-sizing doesn't apply to &lt;object> / &lt;embed><br>
&lt;emilio> RESOLVED: frame-sizing doesn't apply to &lt;object> / &lt;embed><br>
