Autocomplete enter key incorrectly selects first option when popup is closed

[yanmariomenev]

Description

There is an unexpected behavior in the Autocomplete component when interacting with the Enter key after the popup has been closed. Specifically, pressing Enter causes the first option to be selected even though the popup is no longer visible, which is inconsistent with expected behavior.

Steps To Reproduce

1. Open this StackBlitz example or test it on our online demos.
2. Focus on the Countries autocomplete input.
3. Type "a" — the popup will show filtered options like "Albania", "Andorra", etc.
4. Press Escape to close the popup without selecting any option.
5. Press Enter twice.
6. On the second press, the input value changes from "a" to "Albania" unexpectedly.
7. Alternatively, click outside the input to close the popup, then refocus the input and press Enter — the same issue occurs.

Actual Behavior

After closing the popup (via Escape key or clicking outside), pressing Enter still selects the first item in the list, as if the popup were open.

Expected Behavior

When the popup is open, pressing Enter should select the highlighted item.
When the popup is closed, pressing Enter should not select any item or change the input value.
