Steps to reproduce

I tried to use the el-autocomplete tag with the simplest version: an Array returned by the callback function. The suggestion box is visually empty, depite DevTools showing the expected elements in <ElAutocompleteSuggestions> → data → suggestions

What is Expected?

That the suggestions are visible

What is actually happening?

The suggestions, while being apparently present in the dropdown code, are not visible

What needs to be passed via the callback is an Object which must have a property called value. This property holds what is displayed as the suggestion.

For the example above:

filterUsers(user, cb) {
      console.log(user)
      cb([{'value': 'qqq', 'whatever': 'djhjfh'}, {'value': 'zzz', 'whatever': 'uiuiiu'}])
    },

I am not sure the key needs to be value but it looks so.
