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

@skynavga @cconcolato @palemieux ping! 

The TTML2 spec does answer the question:

[`<annotation-position>`](https://w3c.github.io/ttml2/index.html#style-value-annotation-position) says:

> **`outside`**
>
>    Equivalent to `before` for (1) the only line area of or (2) the first line area of the last block area generated by a `p` element which contains annotated text; otherwise, equivalent to `after`.

So I think the answer is it is based on the line areas generated by layout of the base text, with ruby and text emphasis then inserted in the appropriate position as a later step.
