Summary [css-anchor-position-1] Disable auto margins in combination with position-area

Because the default UA styles for popover use `margin: auto; inset: 0`, making popovers integrate usefully with `position-area` requires disabling those margins. The current proposal for doing this is to disable `auto` margins when `position-area` is not `none`. See https://github.com/w3c/csswg-drafts/issues/10258#issuecomment-3374397145
