<!-- NOTE: I'm not using floats in this flex container, since floating
makes it harder to emulate the "stretch" behavior.
(We need to use width: auto - not width:100% - because we need to
allow space for our margins/borders/padding. And width:auto doesn't do
what we want if we're floated.)
However, since our children aren't floated, their adjacent vertical
margins will collapse by default (which doesn't match what happens in
the testcase, since margins don't collapse in a flexbox). So, we
compensate for that by bumping up the margin-top value on every
collapsed top-margin to "4px", which is the total amount of vertical
margin we're expecting between consecutive flex items in the testcase.
(4px = 3px margin-bottom + 1px margin-top)
