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

== [css-flexbox-1] Appendix A: Axis Mappings main-start and main-end 
of column-reverse + wrap-reverse and column + wrap-reverse are the 
same ==
Axis Mappings for ltr + horizontal-tb Writing Mode (e.g. English)

flex-flow | main axis | main-start | main-end
--- | --- | --- | ---
column + wrap-reverse | vertical | top | bottom
column-reverse + wrap-reverse | vertical | top (should be bottom) | 
bottom (should be top)

The following two tables have the same problem.
