Autoform afQuickField not working well with type="select2" and multiple=true.

Nobody has claimed this yet.

Hi,

I am using `afQuickField` with `type="select2"` and `multiple=true`.
#### html:-
`{{> afQuickField name="Country" type="select2" multiple=true select2Options=s2Opts options=optionsCountry }}`

#### js:-
```
s2Opts(){
return {
placeholder: "select upto 8 county",
tags: true
};
},

optionsCountry(){
return [{
label:"India"
value:"india"
},{
label:"North America"
value:"north-america"
},{
label:"South Africa"
value:"south-africa"
},{
label:"China"
value:"china"
},{
label:"Nepal"
value:"nepal"
},{
label:"Shri Lanka"
value:"shri-lanka"
},{
label:"Malesiya"
value:"malesiya"
},{
label:"Afghanistan"
value:"afghanistan"
},{
label:"Canada"
value:"canada"
},{
label:"France"
value:"france"
}];
}

```
#### Schema :-
```
Country: {
type: [String],
optional: true,
maxCount: 8,
autoform: {
label: "Country"
}
},
```

When we select 3 or more countries and click on update button.

### Current Result:-
- It shows only one selected Country which is top in the list among selected Countries.


### Expected Result:-
- It should show all 3 selected Countries after click on update button.

Please advise.

Thanks and Regards,
Saransh

Start by reproducing the reported afQuickField setup with type="select2", multiple=true, select2Options, and the array schema shown in the issue. Trace how the selected values are restored after clicking Update. Done means all selected countries, not only the first, remain selected after the form is updated.
