Re: [csswg-drafts] [css-overflow-3] Standardize `overlay` as a synonym for `auto` (#8063)

The CSS Working Group just discussed ``[css-overflow-3] Standardize `overlay` as a synonym for `auto` ``, and agreed to the following:

* `RESOLVED: overlay is legacy value alias for 'overflow: auto'`

<details><summary>The full IRC log of that discussion</summary>
&lt;fantasai> scribe+<br>
&lt;fantasai> emilio: Was skeptical at first, because I thought only Safari had overlay scrollbars<br>
&lt;fantasai> emilio: but also have classic scrollbars in OS preferences<br>
&lt;fantasai> emilio: so I think aliasing to auto is better<br>
&lt;fantasai> emilio: chrome folks also wanted to do it<br>
&lt;fantasai> emilio: helpful for compat<br>
&lt;fantasai> emilio: only annoyance is it doesn't do what it says<br>
&lt;fantasai> emilio: but we already discussed that tweaking overlay vs non-overlay should be user choice, not author choice<br>
&lt;fantasai> astearns: smfr, anything to add about aliasing 'overflow: overlay' to 'overflow: auto' ?<br>
&lt;fantasai> smfr: I'm in favor. We agree that it should be user choice rather than author choice<br>
&lt;fantasai> smfr: overlay vs non-overlay escaping onto the Web was a mistake<br>
&lt;fantasai> astearns: Proposed to specify 'overflow: overlay' as alias<br>
&lt;fantasai> fantasai: legacy name alias?<br>
&lt;fantasai> emilio: Yeah, I think that would be best<br>

&lt;fantasai> s/legacy name alias/legacy value alias/<br>
&lt;fantasai> https://www.w3.org/TR/css-cascade-5/#value-aliasing<br>
&lt;fantasai> RESOLVED: overlay is legacy value alias for 'overflow: auto'<br>
