Ability to disable SplitButton or Menu items

[fairking]

As SplitButton uses the MenuModel applying disabled: true is not working against dropdown buttons.

<SplitButton label="Save" icon="pi pi-plus" :model="items"></SplitButton>

items: [
    {
        label: 'Update',
        icon: 'pi pi-refresh',
    },
    {
        label: 'Delete',
        icon: 'pi pi-times',
        disabled: true,
    },
]

Tried <Menu> and it looks like the same issue. disabled: true does not do anything.
