**Expected behavior**
Element does not shrink. Same as when 0.001 is passed

**Screenshots**

Start with packages/layout/src/node/setFlexShrink.ts, which the issue identifies as the implementation involved. Reproduce the behavior with flexShrink set to 0 using the linked playground, then verify that the element does not shrink as expected and that the existing nonzero behavior remains unchanged.
