Explanation

I want to create a mix input with multiple duplicates as needed by the user. However the suggestions avoid showing the same tag again if it already exists in the input. I've enabled duplicates as stated in the library.

What I see:

Since First name already exists, the suggestions never show it until I delete it.

<script>
    var whitelist = [
        { text: "account.first_name", value: "Account: First Name" },
        { text: "account.last_name", value: "Account: Last Name" },
        { text: "deal.deal_name", value: "Deal: Name" },
    ];

    var inputElem = document.getElementById('smsBody');
    var tagify = new Tagify(inputElem, {
        mode: 'mix',
        pattern: /@|#/,
        enforceWhitelist: true,
        whitelist: whitelist,
        duplicates: true, //enforced this to allow duplicates
    });

    console.log(tagify.settings.duplicates); //this prints 'true' which means library accepted it

    tagify.on('add', function (e) {
        var tagElm = e.detail.tag;
        var tagType = e.detail.data.text.startsWith('account.') ? 'account' : 'deal';
        tagElm.classList.add('tagify__tag--' + tagType);
    });

    inputElem.addEventListener('change', onChange);
    function onChange(e) {
        document.getElementById("outputValue").innerText = e.target.value;
    }
</script>

They are allowed, they only not being suggested.

You must set the dropdown.includeSelectedTags setting to true manually.

the duplicates setting is only for the tags themselves, unrelated to the suggestions list which has its own setting, because there are scenarios where decoupling those two is needed.
