Headlessui/vue Combobox selects first result when clicking outside

[KYPremco]

I am using the Combobox from the tailwindui form components.
https://tailwindui.com/components/application-ui/forms/comboboxes

In the example mode of tailwindui.com
when you have an item selected and searches for a new one. Then click away from the combobox the previous result will still be selected.

In my own development it will select the first items from the filtered list.

The code from headlessUI gives the same results
