[i18n-activity] The default ruby-position for vertical-lr text may not be over

r12a has just created a new issue for 
https://github.com/w3c/i18n-activity:

== The default ruby-position for vertical-lr text may not be over ==
4.1. Ruby Positioning: the ruby-position property
https://drafts.csswg.org/css-ruby-1/#rubypos

The TTML spec currently specifies that the default for text in 
Mongolian is to put annotations on the left side (the 'before' edge of
 the line box).  CSS Ruby doesn't specifically say that, but implies 
it.

My understanding is that actually the default for Mongolian is more 
likely to be the right side, which i think is `under`.  See an example
 and reasoning at https://github.com/w3c/mlreq/issues/4

I think there should at least be a note in the CSS Ruby spec to warn 
developers that you can't just rely on abstract geometrical 
transformational theories to determine the location of the default 
placement for vertical-lr text.
