Current behavior
On typing the AutoComplete component shows the dropdown. However, to select the first available entry, the user has to use the mouse or click on the arrow down.

Expected behavior
Optionally the first item of the dropdown should be automatically selected

What is the motivation / use case for changing the behavior?
Better UX in some cases: eg to add a list of items, I would like to type some letters, click enter (to add the first entry), type letter, click enter (to add another entry) and so forth.

• Vue version: 3.X
