The logic differs from CSS2 in order to properly handle aspect-ratio and keyword sizes. Each axis can have preferred, min and max sizing constraints, plus constraints transferred from the other axis if there is an aspect ratio, plus a natural and default size. In case of conflict, the order of precedence (from highest to lowest) is:

1. Non-transferred min constraint
2. Non-transferred max constraint
3. Non-transferred preferred constraint
4. Transferred min constraint
5. Transferred max constraint
6. Transferred preferred constraint
7. Natural size
8. Default object size
