[csswg-drafts] [css-sizing] Computing min-width/min-height: auto to zero

fantasai has just created a new issue for https://github.com/w3c/csswg-drafts:

== [css-sizing] Computing min-width/min-height: auto to zero ==
When exactly does 'auto' compute to zero?


The  wording in Flexbox https://www.w3.org/TR/css-flexbox-1/#min-size-auto isn't particularly clear.

> On a flex item whose overflow is visible in the main axis, when specified on the flex item’s main-axis min-size property, specifies an automatic minimum size. It otherwise computes to 0 (unless otherwise defined by a future specification). 

Does it compute to zero
- on flex items, in the main axis, when 'overflow' is visible?
- on flex items, in the main axis always, but not in the cross axis? (Firefox does this)
- on flex items, in both axes? (Chrome does this)

We should probably bias towards computing to `auto` in as many cases as is Web-compatible, but we should also fix the spec to say exactly what happens.
