[csswg-drafts] [css-tables] 2.2.1 Add in caveat for flex and grid items

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

== [css-tables] 2.2.1 Add in caveat for flex and grid items ==
According to this [resolution from the Paris 
F2F](https://log.csswg.org/irc.w3.org/css/2015-08-25/#e581286), the 
fixup is not as clean in a grid or flex context. We need to add this 
to section 2.2.1
