Re: [csswg-drafts] [css-ruby][css-text-decor-4] Add over-most-under-last value to ruby-position & text-emphasis-position for captioning

The Working Group just discussed `Add over-most-under-last value to ruby-position & text-emphasis-position for captioning`.

<details><summary>The full IRC log of that discussion</summary>
&lt;dael> Topic: Add over-most-under-last value to ruby-position &amp; text-emphasis-position for captioning<br>
&lt;dael> github: https://github.com/w3c/csswg-drafts/issues/2998<br>
&lt;dael> astearns: fantasai added to agenda, updates by Nigel<br>
&lt;dael> fantasai: The overall question was to add new value to  ruby position prop to handle ttml behavior. First line has ruby on top, second on bottom. 3+ lines they're all on bottom. Question from WG is do we add it. There's details on how to segment text, block, linebreaks, etc?<br>
&lt;dael> astearns: Is there a use case for changing behavior based on forced line break?<br>
&lt;dael> fantasai: Use case is for captions, don't know what markup looks like. Guessing not on forced line breaks.<br>
&lt;dael> dbaron: I can see why it's useful f or captions, but feels hard to impl for general case. What's previously local now needs bigger area<br>
&lt;dael> florian: Solve by special case first line and having first line be over and rest under?<br>
&lt;dael> florian: Since use case if for 2 line what we do for not 2 lines is error driven by use case so might as well do simple thing<br>
&lt;dael> s/use case if/use case is<br>
&lt;dael> florian: Then again why can't use first-line pseudo<br>
&lt;dael> astearns: First-line psuedo is interesting idea. Gets functionality for block. Do first-line deal with blocks?<br>
&lt;dael> fantasai: Only with firstline of not anon block<br>
&lt;dael> astearns: Then first-line gives us what ttml looking for<br>
&lt;dael> fantasai: I think so. Don't  know nuances of what they're looking for<br>
&lt;dael> astearns: Leave it as a question in the issue? Ask if we can let them do this using first-line<br>
&lt;dael> fantasai: Alright<br>
&lt;dael> florian: Need to make it explicit that this applies  in first-line pseudo.<br>
&lt;dael> fantasai: Have to check pseudo spec. And we can add example in ruby module to show this behavior<br>
&lt;dael> fantasai: I think we need to call it out, not really clear. Have to add it explicitly<br>
&lt;dael> astearns: Poss ttml people considered this and rejected so good to get their feedback on idea<br>
&lt;dael> fantasai: prop: add ruby position to properties applying to first-line, respond to ttml suggesting we use first-lien for this behavior and check if it's a problem<br>
&lt;dael> astearns: It jsut came up, could get shot down as soon as it's o n issue.  not looking for resolution at this point.<br>
&lt;dael> fantasai: We have a proposed resolution and asking for feedback<br>
&lt;dael> astearns: We can come back next week.<br>
