Background

To address other issues, we changed the default for 'flex-shrink' from 0 to 1 during the F2F.

Problem Statement

The behavior of “flex: 0 <length>;” changes - it can now shrink, where before it couldn't.

Proposal(s)

Proposal A: flex-shrink always gets reset to 1, even if flex-grow is 0.
Proposal B: Make an omitted flex-shrink default to 0 if the flex-grow is given as 0 in the flex shorthand.

This issue ties in with the initial values of flex, whose outcome may affect what's sensible here.
