No, I mean ruby-triggered inlinization.  Gecko does in fact do all the computed display bits first, before we start doing anything with boxes, because sanity.

That's not what https://drafts.csswg.org/css-ruby/#anon-gen-inlinize says to do (only block-level things are inlinized, and table-cell is not block-level), and not what Firefox does.  Simple testcase (using table-row instead of table-cell because it's clearer to eyeball):

    <span style="display: ruby-text-container">
      <span style="display: table-row">First</span>
      <span style="display: table-row">Second</span>
    </span>

that generates an anonymous inline-table around the two rows in Firefox, I'm pretty sure.  But that's not defined sanely in any spec, because CSS anon box creation doesn't know about new display types either....

> The Ruby draft text is old 

It claims to be dated today.  ;)  Anyway, clearly changes to the ruby draft are needed; we all agree on that, which is good.

> this is precisely what https://drafts.csswg.org/css-display/#intro says

That's pretty helpful, yes.  It would be even better if all fixup definitions linked to it so you could go from a thing you're looking at to the thing that defines how the thing you're looking at fits into the world.

And again, adding a fixup should be a sane process, which means being able to easily determine what other fixups it needs to interact with.
