[css-layout-api] Example 12 typo?

The --ident example has:

            // Check if we have gone over the block fragmentation limit.
            if (constraints.blockFragmentationType != 'none' &&
                blockOffset > constraints.blockSize) {
                break;
            }

Should constraints.blockSize be constraints.availableBlockSize?
