reference case 1

Here's a reference case, with the "width: 1000px" removed.

I'd expect the testcase to render just like this reference case -- the 1000px shouldn't impact the minimum size that we clamp shrinkage at.

Relevant spec text:
  # auto
  #  When used as the value of a flex item's min main size property,
  # this keyword indicates a minimum of the min-content size, to help
  # ensure that the item is large enough to fit its contents.
  #
  # It is intended that this will compute to the ‘min-content’ keyword
  # when the specification defining it (Writing Modes Appendix D) is
  # sufficiently mature. 

So "min-width: auto" is supposed to effectively compute to "min-width: min-content".

And when we resolve "min-width: min-content", I believe we're supposed to only use the contents of the block -- the computed value of "width" shouldn't affect the calculation.  (If it did, then "width: min-content" would have a circular dependency.)
