Combobox implementation of Autocomplete Country Dropdown

[andelopes]

Hi all,

Wanted to discuss my implementation of a Country Dropdown using the Paste Combobox.

I've implemented functionality that resembles Material UI's Autocomplete and wanted feedback on the interaction and implementation. This is related to the "Buy a Number" improvements in Console.
