1)  Say I have this:

   <div style="display:ruby"><div style="display: ruby"></div></div>

Stepping through the section 2.2 algorithm, step 3 explicitly does 
nothing in this case, since it excludes "ruby containers".  Steps 4 and 
5 are not relevant since there is no white space.  Step 6 is not 
relevant because there are no ruby bases and no white space.  Step 7 is 
not relevant because there are no ruby containers (base or annotation) 
and no white space.

So the upshot is that this box structure is left as-is.  Is this 
actually purposeful?  I would have expected the inner ruby container to 
get wrapped in a ruby base and ruby base container...

2)  Assuming #1 gets addressed as I suggest, I believe the definition of 
"inter-level whitespace" can be simplified to two patterns:

   I. Next box is ruby annotation container
   II. Next box is ruby annotation an previous box is ruby annotation
       container.

   Any intra-ruby white space whose immediately following sibling is a
   ruby annotation container or whose imme

3)  The table in step 5 doesn't say what happens to intra-ruby white 
space which has a ruby base previous box and ruby base container next 
box (or vice versa).  Either it should classify it (most likely), or 
this white space should be removed as inter-level white space?  Or does 
it just hang around as ruby bases?

4)  What should happen to whitespace between two consecutive ruby base 
containers?

5)  This markup:

   <div style="display:ruby">
     <div style="display: ruby-text"></div>
     <div style="display: ruby-text"></div>
   </div>

and this markup:

   <div style="display:block">
     <div style="display: ruby-text"></div>
     <div style="display: ruby-text"></div>
   </div>

   have quite different behavior per current spec: the former ends up 
with a single ruby annotation container containing both kids, while the 
latter ends up with two ruby containers each of which contains a single 
ruby annotation container containing a single ruby annotation.  Is that 
the desired behavior in this case, or a spec bug?  This bit seems 
related to the issue in
