Do not let elements inside display:none subtrees become focus targets. The HTML focusable-area model only allows elements to be focusable when they are rendered, delegate rendering to their children, or are relevant canvas fallback content. Preserve blur for the current focused area after script hides it, since the unfocusing steps operate on the old focus target. Check display:none through the flat-tree style parent chain, so slotted controls inside hidden slot subtrees cannot become focused. Cover hidden ancestors with materialized computed style, display:none controls, display:contents, hidden focused controls, and slotted cases inside hidden and visible shadow-tree subtrees.
