/* Total min content size is larger than available size. Shrink
proportionally to min sizes. Note that max content sizes don't affect
sizing in this mode.
Left margin box min: 18em
Center margin box min: 12em
Right margin box min: 6em
Flex will be the same as min.
First resolve the width of center, by evaluating how much space the
double of each side box would take up. Pick the larger (to preserve
centering), and subtract that from available space.
Available space: 20em
Center flex: 12 (like min)
Left double min (and flex factor): 18em * 2 = 36em
Total flex left double + center: 36 + 12 = 48
Unused space with double left: 20em - 36em - 12em = -28em
Width of double left: 36em + (-28em) * 36 / 48 = 15em
Right double min (and flex factor): 6em * 2 = 12em
Total flex right double + center: 12 + 12 = 24
Unused space with double right: 20em - 12em - 12em = -4em
Width of double right: 12em + (-4em) * 12 / 24 = 10em
Width of double left (15em) is larger than width of double right
(10em). Pick this one and resolve center, by using those flex values.
Width of center: 12em + (-28em) * 12 / 48 = 5em.
Left and right will share the rest, i.e. 7.5em on each.*/
