<!--
|
|
This testcase tests the used value of "min-height:auto" (the property's
|
|
initial value) on flex items in a vertical flex container.
|
|
|
|
It's supposed to resolve to the smallest of:
|
|
a) The used 'flex-basis' (taken from 'height'), if 'flex-basis' is at its
|
|
initial value.
|
|
b) The computed 'max-height' property
|
|
c) If there's no intrinsic aspect ratio: the item's min-content height.
|
|
d) If there is an intrinsic aspect ratio: the item's height derived from
|
|
the ratio & constraints in the other dimension.
|
|
|
|
We measure what the used value is by putting flex items in a small flex
|
|
container, which will shrink its items down to their min-height.
|
|
|
|
This test checks for situations where we should resolve the min-height as
|
|
(a), (b), or (c) above. Another test will check (d).
