<!-- Adding a small min-size shouldn't affect that. -->

<!-- ...nor should a large max-size. -->
<div class="flexbox" style="max-height: 300px">
<div class="a"/><div class="b"/><div class="c"/>

<!-- OK. Now, if we set a minimum size that's larger than the shrinkwrap
size, we should jump up to that size.-->
<div class="flexbox" style="min-height: 120px">
<div class="a"/><div class="b"/><div class="c"/>

space. -->

min-size smaller than the sum of the items' base sizes... -->
