>+        This patch implements layout containment as specified[1].
>+        It adds shouldApplyLayoutContainment to check whether the
>+        element applies for layout containment. Is so, then:
>+        - an independent formatting context is established.
>+        - any overflow is treated as ink overflow.
>+        - an absolute positioning and fixed positioning
>+        containing block is established.
>+        - a stacking context is created.
>+        - for baseline handling, the box is treated as having no
>+        baseline. For grid/flexible box containers/items, this needs
>+        a baseline synthesized from the border edges [2], for buttons it
>+        requires a baseline synthesized from the margin edges [2, 3].
