Multiselect - Filter - Duplicate keys on search.

[botmaster]

Describe the bug

Hello,
I think I've found a bug with the multiselect filter.
If several options have the same name, the filter returns the same item several times when you start typing.
I think that the v-for used to generate the sugested list use the wrong key.

const cities = ref([
  { name: 'New York', code: 'NY' },
  { name: 'New York', code: 'NY1' },
  { name: 'New York', code: 'NY2' },
  { name: 'New York', code: 'NY3' },
  { name: 'Rome', code: 'RM' },
  { name: 'Rome', code: 'RM1' },
  { name: 'Rome', code: 'RM2' },
  { name: 'Rome', code: 'RM3' },
  { name: 'London', code: 'LDN' },
  { name: 'Istanbul', code: 'IST' },
  { name: 'Paris', code: 'PRS' },
]);
