The CSS Working Group just discussed `[selectors] Define how "legacy aliases" work on selectors.`, and agreed to the following:

* `RESOLVED: convert at parse time`

<details><summary>The full IRC log of that discussion</summary>
&lt;dael> Topic: [selectors] Define how "legacy aliases" work on selectors.<br>
&lt;dael> Rossen_: Is emilio on?<br>
&lt;dael> [waiting for emilio to join]<br>
&lt;dael> github: https://github.com/w3c/csswg-drafts/issues/5847<br>
&lt;dael> emilio: Have a couple places where we define a selector where for legacy reason can be impl as alias but no definion of that.<br>
&lt;dael> emilio: Came up as I did compat work on other pseudo classes.<br>
&lt;dael> emilio: Compat can change what needs to be done but seems as if we should have guidance on how this should work<br>
&lt;dael> emilio: afaict two options are keep zeroizing the non-standard or convert them at parse time<br>
&lt;dael> emilio: Some inconsistencies in Blink. Gecko should always turn it intot he stanrdard at parse time. I think that's what we do for properties in general<br>
&lt;dael> Rossen_: Prop is align more closely with converting at parse time<br>
&lt;dael> Rossen_: Questions or should we resolve on that?<br>
&lt;dael> Rossen_: I'll take silence as no<br>
&lt;dael> Rossen_: No comments or objections?<br>
&lt;dael> Rossen_: I see support in GH from TabAtkins<br>
&lt;dael> RESOLVED: convert at parse time<br>
