For the "Advanced" demo in https://www.primefaces.org/primereact/#/dropdown

Current behavior

1. enter something in the filter, for example "a"
2. use arrow key to move to the item, for example "Jaguar"

Now after pressing the enter key to confirm the selection, the dropdown menu does not go away.

Note: Without the filter, the dropdown menu is closed after pressing Enter.

Expected behavior

The dropdown menu should always be closed after pressing Enter.
