This reverts commit 6a80c15b5b5efe5ff39812a018114e8bdc1dc0cf.
- Avoid returning a NaN flexShrinkAdjustment.
- Bail early (instead of assert) if a line has a positive `flexFactorSum` but then no flexible item can be found via flex adjustments, for example because the flexible items have zero size.
- Continue flexing other lines when one line is inflexible.
- Add unit test for the first 2 fixes.
