Re: [csswg-drafts] [css-overflow-4] Clamping floats in 1d or 2d (#13668)

The CSS Working Group just discussed `[css-overflow-4] Clamping floats in 1d or 2d`, and agreed to the following:

* `RESOLVED: floats are only clipped at block-end edge, allow overflowing in other edges`

<details><summary>The full IRC log of that discussion</summary>
&lt;TabAtkins> florian: a while back we resolved that when you're clamping and there's a float that possibly goes beyond clamp point<br>
&lt;TabAtkins> florian: instead of earlier behavior - clamp the text but expand element to clear the float - we want to instead clamp the float at the content edge<br>
&lt;TabAtkins> florian: that was our resolution. but we just discussed block direction<br>
&lt;TabAtkins> florian: didn't discuss other directions<br>
&lt;TabAtkins> florian: so what happens if you also overflow in inline<br>
&lt;TabAtkins> florian: suspect we want to let it happen, that's the general clamping beahvior, it only limits you in block<br>
&lt;TabAtkins> florian: I think it makes sense to maintain that principle here<br>
&lt;TabAtkins> florian: andreu had a follow-up question of it it clamps in block-end only, or if block-start clamp if you relpos it up or something<br>
&lt;TabAtkins> florian: so first, inline direction. do we want to allow overflow?<br>
&lt;TabAtkins> astearns: makes sense to limit it to block direction<br>
&lt;fantasai> TabAtkins: This doesn't affect inline axis in any other context<br>
&lt;fantasai> TabAtkins: Same with block-start direction<br>
&lt;fantasai> TabAtkins: It doesn't affect those directions otherwise, so we shouldn't care here either<br>
&lt;fantasai> &lt;fantasai> +!<br>
&lt;TabAtkins> andreubotella: to me the clipping proposed feels a bit werid<br>
&lt;fantasai> s/!/1/<br>
&lt;TabAtkins> andreubotella: but it makes sense probably to only happen in block<br>
&lt;TabAtkins> andreubotella: and if you relpos it up to the corner, you just start clipping at the edge line<br>
&lt;TabAtkins> florian: yep<br>
&lt;TabAtkins> florian: so proposed resolution is floats are only clipped at block-end edge, allow overflowing in other edges<br>
&lt;TabAtkins> astearns: objections to modifying previous resolution?<br>
&lt;TabAtkins> RESOLVED: floats are only clipped at block-end edge, allow overflowing in other edges<br>
