[css3-flexbox]shrinking flex:0 items

I have noticed that Webkit flexbox implementation (the old-spec) will shrink items with zero flexibility when there are no flexible items, or all flexible content has reached min-width.

Is that a desired behavior? I seems useful, probably a good default. It may be worth considering for standard behavior.

I think I am more against it than for it - it is usually a good experience, but it muddles the concept of "no flexibility". If somebody wants that behavior, they can use very small flexibility.
