Re: [csswg-drafts] [css-text-decor-4] Are text decorations visual overflow or layout overflow? (#3272)

The CSS Working Group just discussed `Are text decorations visual overflow or layout overflow?`, and agreed to the following:

* `RESOLVED: text decoration is considered ink overflow and not layout`

<details><summary>The full IRC log of that discussion</summary>
&lt;dael> Topic: Are text decorations visual overflow or layout overflow?<br>
&lt;dael> github: https://github.com/w3c/csswg-drafts/issues/3272<br>
&lt;dael> Rossen: Raised by myles, fantasai added<br>
&lt;dael> fantasai: myles and I agree it should be ink overflow. Wnat to confirm with WG. I think add to L3 and L4<br>
&lt;dael> Rossen: Implication is if you're editing and at the end of a scrollable paragraph and what I type in becomes underlined because syntax I won't be able to see that by scrollbar.<br>
&lt;dael> fantasai: If you choose and offset that places underline outside of linebox.<br>
&lt;dael> fantasai: Underline typicially in linebox and that's within scrollable. You'd have to place the underline below the line height before it disappears<br>
&lt;dael> Rossen: Trying to understand if we're okay with that<br>
&lt;dbaron_> It might also be fun to define what element they're overflow from.<br>
&lt;dael> fantasai: I think it's fine. If you're placing the underline that low you're asking for trouble<br>
&lt;dbaron_> But happy with ink overflow, I think<br>
&lt;dael> Rossen: [Reads dbaron_ ]<br>
&lt;dael> fantasai: Given painted at same layer as text, should overflow from element painting the text<br>
&lt;dael> Rossen: Certainly content layer of the scroller...let's see<br>
&lt;fantasai> https://www.w3.org/TR/CSS2/zindex.html#each-box<br>
&lt;dael> Rossen: Should be container of element with text.<br>
&lt;dael> Rossen: Objections to resolving on definition that text decoration is considered ink overflow and not layout<br>
&lt;dael> RESOLVED: text decoration is considered ink overflow and not layout<br>
