dbaron has just created a new issue for 
https://github.com/w3c/csswg-drafts:

== [css-color][css-tables] should 'opacity' be hoisted from the table 
box to its wrapper box ==
CSS 2.1 specifies, in the rules on tables, a list of properties that, 
when specified on a table, apply to the table wrapper box rather than 
the table box.

css-color-3 introduces the opacity property.

I haven't tested carefully yet, but 
https://bugzilla.mozilla.org/show_bug.cgi?id=1286803 suggests that 
some but not all browsers include 'opacity' in the list of properties 
to be hoisted to the table wrapper box.  Doing so produces the 
expected results, in that the caption (inside the table) gets included
 in the effect of 'opacity'.

I suspect specifying this is the right thing to do, but further 
testing (e.g., making sure that the implementations that apply the 
opacity to the caption are actually doing correct group opacity when 
the table and caption overlap) is probably warranted first.
