Will align contentNode with referenceNode (invokerNode by default) for local overlays.
Usually needed for dropdowns. 'max' will prevent contentNode from exceeding width of
referenceNode, 'min' guarantees that contentNode will be at least as wide as referenceNode.
'full' will make sure that the invoker width always is the same.
@type {'max' | 'full' | 'min' | 'none' | undefined }
