content-visibility: Avoid updating style in hidden subtrees for focus.

This patch ensures that we first check whether the element is in a
hidden subtree that prevents focus activation before forcing a style
and layout tree update.

This means that we can now set a content-visibility: hidden on a
container which has a currently focused element and it will clear
that focused element without first updating style and layout
tree in the subtree (due to a check whether the currently focused
element is focusable).
