Re: [csswg-drafts] [css-contain] contain:paint should use padding box instead of content box

The Working Group just discussed `CSS-Contain`, and agreed to the following resolutions:

* `RESOLVED: align to overflow:clip behavior`

<details><summary>The full IRC log of that discussion</summary>
&lt;dael> Topic: CSS-Contain<br>
&lt;florian> github: https://github.com/w3c/csswg-drafts/issues/2223<br>
&lt;dael> florian: currently contain:paint clips tot he content box which is different from overflow. WE should prob use padding box as well.<br>
&lt;dael> florian: WE should be clipping to the shapped padding box like overflow<br>
&lt;dael> fantasai: Can't you invoke overflow clip?<br>
&lt;dael> florian: At some point we defined paint containment to be at computed value time, but we do want the same effect. How it's desc doesn't matter.<br>
&lt;dael> fantasai: I'd say used value time.<br>
&lt;dael> dbaron: Shapped padding box?<br>
&lt;dael> florian: Padding box with border radius applied.<br>
&lt;dael> dbaron: Sounded related to shapes.<br>
&lt;dael> florian: No, it's just a piece of termonology we resolved to add.<br>
&lt;dael> [questions about what we resolved]<br>
&lt;dael> florian: We resolved to add a term, I proposed shaped-padding-box but I'm open to other names.<br>
&lt;astearns> yesterday: https://github.com/w3c/csswg-drafts/issues/2324#issuecomment-380036663<br>
&lt;dael> dbaron: Not crazy about that because it sounds like shapes.<br>
&lt;dael> florian: So the padding box with rounding corners applied and if there's ever other types of corners those as well.<br>
&lt;dael> florian: Resolve to align to overflow:clip behavior?<br>
&lt;dael> Rossen: Obj?<br>
&lt;dael> RESOLVED: align to overflow:clip behavior<br>
