[css-flexbox] Making percentage margins/padding consistent with Grid

Right now, Flexbox treats vertical percentage margins and paddings
same as block layout - they're resolved relative to the width of the
containing block.  Grid instead makes vertical margin/padding resolve
their percentages against the height of the containing block.

I think this is a reasonable behavior, and would like to copy it into
Flexbox.  (In general, I'd like Grid and Flexbox to be identical in
these kinds of details unless there's a great reason for the
difference.)

Thoughts?
