In "normal flow", if an element has a :hover rule, it is applied when moving the mouse over it's children too, even if they are not geometrically inside the box of their parent (e.g. positioned elements, etc.)

However, if the children are flowed in a region while their parent is still in normal flow, the :hover state is not triggered on the parent (when moving the mouse over its children).

If both the parent and it's children are in a named flow, the :hover state gets triggered as usually.
